# Spatial Memory and the First Brain: The Method of Loci

> **TL;DR** The method of loci, or memory palace, works because the brain is a spatial processor that remembers places far better than abstract facts. To use it: pick a familiar place, define a fixed route of distinct locations, place a vivid exaggerated image of each thing to remember at each spot, then mentally walk the route to recall. It has strong evidence behind it and is the gateway to placing concepts in mental space, the spatial substrate of a First Brain.

## How to use the method of loci

The method of loci, also called the memory palace, turns the brain's strongest faculty, spatial memory, into a tool for remembering almost anything. It works in five steps, and you can build your first one in an afternoon.

First, choose a place you know intimately, like your home, somewhere you can walk through with your eyes closed. Second, [define a fixed route through it](https://artofmemory.com/blog/how-to-build-a-memory-palace/) and pick out a series of distinct locations along the way: front door, coat rack, kitchen sink, sofa, and so on, ten to fifteen for a first palace. Third, walk that route mentally several times until the order is automatic. Fourth, for each thing you want to remember, create a vivid, exaggerated mental image and place it at one of those locations, interacting with the spot in some absurd, memorable way. Fifth, to recall, walk the route again and read off the images. The technique has [strong evidence behind it](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12514325/), producing large gains in recall over rote rehearsal in controlled studies.

## Why it works: the brain is a spatial processor

The reason this ancient trick beats brute repetition is that you are using the right hardware. The human brain evolved to navigate physical space, and it [remembers places and routes far more readily than abstract facts](https://cognitivetrain.com/method-of-loci/). The method of loci hijacks that spatial system, the same machinery behind your sense of direction, and uses it to carry information it was never designed to hold. You are not asking memory to do something hard; you are giving it something it already does effortlessly.

This is why the technique pairs so naturally with vivid imagery. Distinctive, exaggerated images are remembered better than plain ones, as we covered in [the anime brain](/journal/the-anime-brain-intense-visualization-for-memory/), and the same spatial faculty is the one you strengthen by [navigating without GPS](/journal/navigating-without-gps/).

| Step | What you do | Why it works |
| --- | --- | --- |
| 1. Choose a place | Pick a location you know by heart | Leverages existing spatial memory |
| 2. Set a route | Define ordered, distinct loci | Gives recall a fixed sequence |
| 3. Learn the route | Walk it mentally until automatic | Makes the structure effortless |
| 4. Place vivid images | Encode items as exaggerated scenes | Distinctiveness boosts memory |
| 5. Walk to recall | Retrace the route and read off images | Spatial cues trigger retrieval |

## Placing concepts in mental space

The memory palace is the gateway to a larger skill: placing concepts in mental space on purpose. A First Brain is, in part, a spatial map of knowledge, a cognitive map where ideas have positions and neighbors, which is exactly why the brain's navigation system also organizes abstract thought. Training the method of loci trains the same faculty you use to lay out and traverse your knowledge, the connecting and mapping work of [cognitive mapping](/journal/cognitive-mapping-how-to-build-your-first-brain/). Even physically engaging the body deepens it, the embodied effect we explored in [tactile note-taking](/journal/tactile-note-taking/), and the same spatial faculty can be strengthened even through play, as the brain-imaging work on [why Tetris is good for the brain](/journal/tetris-and-spatial-graphing/) shows. Learn to place things in mental space, and you have learned the substrate of a First Brain. That is the argument of [Building Your First Brain](/), free for the first 1,000 readers.

## Frequently asked questions

### How do you use the method of loci?

In five steps: choose a place you know well, define an ordered route of distinct locations within it, memorize the route, place a vivid and exaggerated mental image of each item you want to remember at each location, then mentally walk the route to recall them. As Building Your First Brain by Lawrence Arya frames it, this trains the spatial faculty that also lets you place concepts in mental space, the substrate of a First Brain.

### Does the memory palace technique actually work?

Yes. A systematic review and meta-analysis found the method of loci produces a large improvement in recall compared with simple rehearsal, and brain imaging shows it engages the spatial and navigational systems. It is one of the best-evidenced memory techniques and has been used by memory champions for exactly this reason.

### Why does the method of loci work?

Because it uses the brain's strongest faculty. Humans evolved to navigate and remember physical space far better than abstract facts, so placing information at locations along a familiar route lets you recall it using spatial memory rather than fragile rote repetition. You are giving memory a task it is built for.

### What can you memorize with a memory palace?

Almost anything you can turn into images and order: speeches, lists, vocabulary, sequences of facts, the order of a deck of cards, exam material. It is especially powerful for ordered information, because the route itself encodes the sequence. With multiple palaces you can store large amounts without them interfering.

### How many memory palaces do you need?

Start with one and reuse it as you learn the technique. As you store more material, build additional palaces from other familiar places so that different bodies of information do not blur together. Experienced practitioners maintain many palaces, each dedicated to a particular subject or set of memories.
