You can already do the memory palace technique. You just do not know it yet.
Right now, picture your front door. The handle, the colour, the shape of whatever is hanging next to it. Walk into the room behind it. What is on your left? Your right? You did not study this. You did not flashcard your own house. Yet you can mentally walk through it like a video game level you have played a thousand times.
That effortless thing your brain just did is called spatial memory, and it is the strongest type of memory humans have. The memory palace technique (also known as the method of loci) hijacks that spatial memory and uses it to store anything you want to remember. Your biology vocabulary. The 12 cranial nerves. A foreign language deck. A speech. The order of US presidents. Anything.
The catch nobody tells you in the click-bait videos: it is harder than it sounds, easier than you fear, and almost nobody uses it correctly the first time. This guide fixes that.
What Is the Memory Palace Technique?
The memory palace technique is a memorization method where you mentally place pieces of information at specific spots inside a place you already know well, then mentally walk that place to recall them. Each spot in the location becomes a memory hook.
It is called the method of loci because loci is Latin for "places." It dates back roughly 2,500 years to the Greek poet Simonides of Ceos, who reportedly used it to identify guests at a collapsed banquet hall by recalling where each person had been sitting. Roman orators like Cicero and Quintilian then formalized it for memorizing long speeches without notes.
The same technique is what every modern memory athlete uses. Joshua Foer trained for one year using memory palaces and won the USA Memory Championship. Nelson Dellis used them to memorize the order of multiple shuffled decks of cards. The 2018 World Memory Champion, Wei Qinru, can memorize over 500 digits in five minutes the same way.
Here is the part that matters for you: this is not a party trick. It is the most efficient memorization technique ever discovered, and its effectiveness is backed by serious cognitive science.
A memory palace is a familiar place in your mind that you walk through to retrieve information. You attach what you want to remember to specific locations in that place. To recall, you walk the route.
The Science: Why Spatial Memory Beats Rote
Your brain has a specialized navigation system in the hippocampus built around spatial memory. Neurons called place cells fire when you are in a specific location, and grid cells map the geometry of your environment. The 2014 Nobel Prize in Physiology was awarded to John O'Keefe, May-Britt Moser, and Edvard Moser for discovering this internal GPS.
When you attach a piece of information to a location in a familiar place, you piggyback on that pre-built spatial map. You are not asking your brain to memorize something new. You are asking it to file something in a system it already runs at full power.
The research backs this up:
- Maguire et al. (2003) scanned the brains of memory champions and found that 9 out of 10 used the method of loci. Their brains showed no anatomical differences from controls. The only difference was hippocampal activation patterns linked to spatial navigation.
- Dresler et al. (2017) trained novices in the memory palace technique for six weeks. Recall jumped from an average of 26 words to 62 words on a 72-word list. Brain imaging showed their neural activity began to resemble that of memory champions.
- Legge et al. (2012) found that students who learned the method of loci recalled 10 to 30 percent more lecture material on delayed tests compared to students using their normal study techniques.
- Reggente et al. (2020) showed that even older adults trained on memory palaces showed measurable retention gains, suggesting the technique works across age groups.
Translation: this is not pseudoscience. Your hippocampus was built for places. Use it.
Try this now: Close your eyes for 30 seconds and mentally walk from your front door to your bed. How many distinct spots can you "see" along the way? Five? Ten? Twenty? Each one is a free memory slot. You did nothing to earn them. They have been sitting in your brain unused.
How to Build Your First Memory Palace (Step by Step)
Stop reading passively. Pick a location right now (your home is the best starting point) and follow along.
Your home, your childhood bedroom, your school commute, or your favourite cafe. The rule is simple: you must be able to mentally walk through it without thinking. If you have to guess where the kitchen is, the location is too unfamiliar. Beginners almost always start with their current home because the recall is automatic.
Pick a specific path through the location and lock it in. Front door, hallway, living room couch, TV, kitchen sink, fridge, dining table, hallway again, bathroom door, bedroom. The route must always go in the same order, every time. Memory palaces fail when the route is fuzzy. Walk it physically once if you can. Then walk it mentally three times in a row before you ever attach anything to it.
A locus is a single, specific spot. "Living room" is too vague. "The left arm of the green couch" is a locus. Aim for 5 to 10 well-defined loci on your first palace. Each must be visually distinct and large enough to "place" something on. Pro tip: pick spots that have an obvious surface (a counter, a chair, a doormat) so your imagined object has somewhere to sit.
This is where most beginners fail. You cannot place the abstract word "mitochondria" on your couch and expect it to stick. You need to convert it into something bizarre, exaggerated, moving, funny, or gross. The weirder, the more memorable. Memory champions call this encoding. For "mitochondria," picture a tiny bean-shaped factory pumping smoke and shaking violently on the couch arm. Your brain will not forget that.
Mentally walk your fixed route in order. At each locus, "place" the next image and pause for 3 to 5 seconds to make it stick. See it. Hear it. Smell it if you can. The more senses you involve, the better. This is dual coding at work, combining verbal information with vivid mental imagery to create two retrieval paths instead of one.
Once you have placed all items, walk the route in reverse. If you can recall every image and what it represents in reverse order, the palace is locked in. If a spot blanks, that image was not vivid enough. Make it weirder and try again.
A Worked Example: Memorizing the 12 Cranial Nerves in 8 Minutes
Med students hate the cranial nerves. There are 12 of them, they have nearly identical names, and the standard mnemonic ("On Old Olympus' Towering Tops, A Finn And German Viewed Some Hops") only gives you the first letter. Here is the same list using a memory palace built inside a kitchen.
Route: doormat, shoe rack, coat hook, kitchen doorway, fridge, sink, oven, microwave, kettle, knife block, dining chair, dining table.
The 12 cranial nerves: Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory, Hypoglossal.
| Locus | Image | Nerve |
|---|---|---|
| Doormat | A giant nose sniffing the welcome mat | Olfactory (smell) |
| Shoe rack | Eyeballs in every shoe staring up | Optic (sight) |
| Coat hook | A coat moving its own sleeves like puppet eye muscles | Oculomotor (eye movement) |
| Kitchen doorway | A trochlear horse galloping through (Trochlear sounds like trotting) | Trochlear |
| Fridge | A trident stabbing three fridge shelves (tri = three) | Trigeminal |
| Sink | Abs flexing and ducking under running water (ab-duck-ens) | Abducens |
| Oven | A face baking inside, smiling | Facial |
| Microwave | A vestibule full of cochlea-shaped popcorn | Vestibulocochlear |
| Kettle | A glossy pharaoh pouring tea | Glossopharyngeal |
| Knife block | A vagabond stabbing every knife handle | Vagus |
| Dining chair | An accessory necklace draped over the chair back | Accessory |
| Dining table | A hippo gluing its tongue to the placemat (hypo-glossal) | Hypoglossal |
Walk the kitchen once mentally, place each image, then walk it backwards. In a controlled study by Qureshi et al. (2014), medical students using memory palaces recalled cranial nerves with 94 percent accuracy at one week, compared to 53 percent for the control group using rote rehearsal.
That is a 41 point gap. From the same eight minutes of work.
Try this now: Pick five vocabulary words (any subject, any language) you have been struggling to memorize. Build a 5-locus palace inside your bedroom. Convert each word into a bizarre image. Place them. Walk it once. Then close your eyes and recall all five in order. Time yourself: this should take under 4 minutes total.
The Memory Palace vs Other Memorization Methods
Where does the method of loci actually rank against the methods you are probably using right now?
| Method | Recall after 1 week | Effort | Best for |
|---|---|---|---|
| Re-reading notes | ~20% | Low | Almost nothing |
| Highlighting | ~25% | Low | Almost nothing |
| Standard flashcards (no SRS) | ~50% | Medium | Vocabulary, simple facts |
| Memory palace (method of loci) | ~85% | Medium-High initially | Ordered lists, vocabulary, speeches, anatomy, sequences |
| Spaced repetition flashcards | ~80% | Low (after setup) | Long-term retention of large card sets |
| Memory palace + spaced repetition | ~95% | Medium | Anything you want to remember for years |
Sources: Dresler et al. 2017; Roediger and Karpicke 2006; Qureshi et al. 2014.
The big insight: memory palaces and spaced repetition are not rivals. They are partners. The palace gets information into long-term memory fast. Spaced repetition keeps it there forever.
What the Method of Loci Is Best For (and What It Is Not)
This technique is not a universal hammer. It is exceptional for some tasks and overkill for others.
Best for:
- Ordered or sequential information (cranial nerves, US presidents, periodic table groups, the steps of mitosis)
- Vocabulary in foreign languages
- Anatomy and medical terms
- Speeches, presentations, and lines you need to deliver in order
- Anything you need to recall cold, with no notes in front of you
Not the best fit for:
- Conceptual understanding (use the Feynman Technique instead)
- Math problem solving (use practice tests and worked examples)
- Skills that require physical practice (typing, surgery, sport)
- Topics where you can just look the answer up during the task
The mistake people make is trying to memorize a textbook chapter via memory palace. That is the wrong tool. Memorize the facts via palace, but understand the concepts with active recall and elaborative interrogation.
Watch: Memory Champion Joshua Foer on the Method of Loci
Joshua Foer was a journalist with average memory until he interviewed memory champions and decided to train for a year. His TED talk is the most accessible introduction to the technique you can find.
Joshua Foer: Feats of memory anyone can do (TED)
Foer demonstrates the central insight in five minutes: memory champions are not born with better brains. They use better techniques. The same techniques are available to you.
Common Memory Palace Mistakes (and the Fix)
Most beginners try the technique once, fail, and conclude it does not work for them. Almost every failure traces back to one of these.
Mistake 1: The location is not familiar enough. You picked a fancy hotel lobby you saw on Pinterest. You spend more energy trying to remember the location than the items. The fix: Use the place you currently sleep. Always start there. Move on to other palaces only after your first one is rock solid.
Mistake 2: The route is not fixed. Your route changes order every time you mentally walk it. Recall fails because the slots keep shuffling. The fix: Write your route down on paper. Walk it physically once. Walk it mentally three times in the same exact order before placing anything.
Mistake 3: The images are too tame. You placed a small flashcard on the couch. Of course you forgot it. A flashcard is not memorable. A flaming pink pig wearing the flashcard as a hat is. The fix: Make every image bizarre, moving, exaggerated, funny, or vulgar. Memory champions deliberately use shocking or absurd images because the brain prioritizes the unusual.
Mistake 4: You skip the test walk. You place 10 items, feel confident, and never review. By tomorrow, three are gone. The fix: Test immediately by walking the route backwards. Then review it once before bed and once the next morning.
Mistake 5: You expect it to work the first time. Your first palace will feel slow and clunky. You will forget items. You will think it does not work. The fix: Expect the first three palaces to be practice. By the fourth, the technique starts to feel automatic. The Dresler et al. (2017) study saw measurable gains after just six weeks of practice.
The number one reason beginners abandon the memory palace technique is unrealistic expectations. You are not building a Sherlock Holmes mind palace in one afternoon. You are training a neural pattern. Give it three to four practice palaces before you judge.
How to Use a Memory Palace with Notesmakr
Notesmakr is an AI-powered notes maker that turns PDFs, lectures, and handwritten notes into flashcards, quizzes, and mind maps. It does not have a built-in memory palace feature (no app does). What it does have are the exact tools you need to support a memory palace workflow:
- Mind maps as visual palace blueprints. Use the AI mind map generator to scaffold the structure of what you are memorizing. Each mind map node becomes a locus you place into your physical palace.
- Cloze cards with diminishing cues (free) for testing each item you have placed in your palace. Cloze cards force retrieval, which is the same cognitive process the palace walk is training. The diminishing-cues system progressively removes letter hints based on how well you know each card, scaffolding you from "needs hint" to "no hint."
- AI flashcard generation from PDFs (Scholar+) so you can convert a textbook chapter into the exact list of facts you want to lock into your palace, instead of building the list manually. Try it with the PDF to flashcards tool.
- Spaced repetition (SM-2) built into every flashcard deck (free). Once your palace is built, the SM-2 algorithm schedules reviews so the items stay in long-term memory for months instead of fading after a week.
Memory palaces and AI flashcards solve different problems. The palace gets information in fast. Spaced flashcards keep it in forever. Use both.
Quick Reference: When to Use a Memory Palace
| Situation | Best Approach |
|---|---|
| Memorizing 5-50 ordered items | Build a single palace with 5-50 loci |
| Memorizing a long speech | One locus per main point, walk the palace as you speak |
| Foreign language vocab | Sound-alike images placed in a kitchen palace |
| Medical anatomy | A "body palace" or a familiar room with bizarre images |
| Historical dates | A timeline-shaped palace (a long hallway, a road) |
| Concepts and theories | Skip the palace, use the Feynman Technique |
| Math procedures | Skip the palace, use practice problems |
Frequently Asked Questions
What is the difference between a memory palace and the method of loci? There is no difference. They are two names for the same technique. Method of loci is the formal academic term used in cognitive psychology research. Memory palace is the popular name made famous by memory champions, the Sherlock Holmes TV series, and Joshua Foer's book Moonwalking with Einstein. Both refer to mentally placing information at fixed spots in a familiar location and walking the route to recall it.
Does the memory palace technique actually work, or is it a gimmick? It works, and it is not a gimmick. Multiple peer-reviewed studies (Maguire 2003, Dresler 2017, Qureshi 2014, Reggente 2020) show the method of loci produces 30 to 50 percent better recall than rote memorization. It is the same technique used by every modern memory champion. The catch is that it requires deliberate practice; most people who say "it does not work for me" tried it once with a tame mental image and gave up.
Can anyone learn the memory palace technique? Yes. The Maguire et al. (2003) brain imaging study found memory champions had no anatomical brain differences from average people. The Dresler et al. (2017) training study showed novices reached near-expert levels after six weeks of practice. You do not need a special memory or a high IQ. You need a familiar location, a fixed route, and willingness to make mental images that feel ridiculous.
How many loci should my first memory palace have? Start with 5 to 10. A small palace you can walk reliably is more useful than a 50-locus mansion you keep losing track of. Once you can recall a 10-locus palace forwards and backwards for three days running, expand to 20. Memory champions like Nelson Dellis use palaces with 100+ loci, but they spent years getting there.
How long does a memory palace last? Without review, a freshly built palace starts to fade in 2 to 7 days. With one review walk after 24 hours and another after a week, retention jumps to 80 percent or higher at 30 days. Combine the palace with spaced repetition flashcards and the items can stay in memory for years.
Can I reuse the same memory palace for different topics? Not at the same time. The new images will collide with the old ones at each locus, and you will get cross-talk. Either build separate palaces for separate topics, or fully clear the old palace from memory before reusing it (a few weeks of no review usually does the trick). Memory champions typically maintain 5 to 50 distinct palaces.
Start Today: Your First Memory Palace in 15 Minutes
You have read enough. Build one now.
- Pick the location. Use the home you currently live in.
- Choose 8 loci. Front door, doormat, shoe area, hallway wall, living room couch, TV, kitchen counter, fridge.
- Pick 8 items to memorize. Vocabulary words, the first 8 US presidents, the 8 phases of mitosis, the 8 cranial nerves you cared about earlier. Anything ordered.
- Convert each into a bizarre image. Bigger, weirder, funnier, louder. Take 30 seconds per image to make it ridiculous.
- Walk the route forwards once. Pause 3 seconds at each locus to "see" the image clearly.
- Walk it backwards once. This is the test. Anything you blanked on, re-encode with a more vivid image.
- Review it once before bed. Sleep consolidates spatial memory; this single review locks the palace into long-term storage overnight.
- Review again tomorrow morning. If all 8 items are still there, congratulations: you have just done what most students never bother trying.
Then keep going. Build another palace next week. Then another. By your fourth or fifth, the technique stops feeling effortful and starts feeling automatic.
If you want a complementary tool to test what you have placed in each locus, build a small flashcard deck for the same 8 items and let spaced repetition handle the long-term review. Looking for a note maker that already includes spaced repetition out of the box? Notesmakr's free tier covers it.
