The Memory Palace: How to Memorize Anything Using Places You Know

In the first century BC, Roman orators memorized entire speeches by imagining a building and placing the points of their speech in different rooms. To deliver the speech, they walked through the building in their mind. The technique is called the Method of Loci, and it works as well today as it did then.

How to build your first palace

The trick is to start with a place you already know cold, not invent one.

1. Pick a familiar place. Your bedroom, your kitchen, your route to class. The more vividly you know it, the better. Most beginners use their own home.
2. Choose a fixed route through it. Front door, hallway, kitchen counter, fridge, table, sofa, TV. Same order every time. Ten to twenty stops is plenty for a first palace.
3. Walk the route once in your mind, naming each stop out loud. This locks the route in.

That's the palace. The structure is empty; now you fill it.

How to populate it

Take the things you want to remember and place one at each stop, in order. Make each image vivid, weird, and interactive. Vague images don't stick; absurd ones do.

Memorizing the first five cranial nerves? At the front door, an enormous olfactory nose. In the hallway, glowing optic eyes on the wall. On the kitchen counter, a tiny oculomotor puppet pulling strings. In the fridge, a trochlear pulley spinning. On the table, a giant trigeminal trident with three prongs.

When you walk the route in your mind, the items come back in order. Not because you tried to memorize them, but because the place you already knew is doing the work.

Why it works

Human spatial memory is enormous. You can wake up tomorrow and recall the layout of a house you lived in twenty years ago. That's not normal memory; that's a specialized system the brain evolved long before lectures and textbooks. The memory palace plugs into it.

The other ingredient is the vivid, strange images. The brain remembers unusual, emotionally-charged things far better than dry ones. A flying olfactory nose is unforgettable; "olfactory nerve" on a page is not.

What to use it for

The technique is at its best for ordered, grouped material you need to recall together: anatomy structures, historical timelines, the steps of a process, vocabulary by theme, the bones in the wrist. Use it where the order matters.

It's less useful for one-off facts you need to recall on a specific cue. Those are flashcard territory. The honest division of labor: memory palace for sequences, spaced flashcards for facts.

Build one palace this week. Use it for the next exam topic that has more than ten ordered items. You'll be surprised how well it holds.

Questions

What is the Method of Loci or memory palace technique?

A memorization method where you imagine a familiar place and mentally place the items you want to remember at specific locations along it. To recall, you walk through the place in your mind and pick up each item.

Does the memory palace technique actually work?

Yes. Memory athletes use it to memorize the order of decks of cards, hundred-digit numbers, and thousands of words. It works because the brain's spatial memory is enormous and well-protected, and the technique hijacks it.

What can students use a memory palace for?

Anything ordered: anatomy structures, historical timelines, vocabulary lists, the steps of a process, the bones in the hand. It's especially powerful for material that has to be recalled in order.

How long does it take to build one?

Building the palace itself takes about ten minutes. Populating it with twenty items takes another ten to twenty. The recall comes back almost instantly with a short practice walk.

Is the memory palace better than flashcards?

Different tools for different jobs. Flashcards are great for one-off facts and spaced retrieval over time. A memory palace is unbeatable for ordered lists and groups of related items you need to recall together.
