The method of loci is a memory technique where you place things you want to remember at specific spots along a familiar route, then mentally walk the route to recall them in order. It’s the “memory palace” method, over 2,000 years old, and still the tool every top memory competitor uses. This guide walks through exactly how to do it.
Where the method comes from
The technique traces to ancient Greece. The story goes that the poet Simonides of Ceos, around 500 BCE, identified guests crushed in a collapsed banquet hall by recalling where each had been sitting. He realized memory attaches strongly to places. Roman orators, including whoever wrote the “Rhetorica ad Herennium” around 80 BCE, wrote it up as a system for memorizing long speeches without notes.
Two thousand years later, nothing better has replaced it for ordered lists. That’s a long track record for one idea.
Why it works
Your memory for places and spatial layouts is unusually strong. You can picture your home’s layout instantly, every room, every doorway, without effort. The method of loci borrows that built-in map and uses it as a filing system. Instead of remembering a bare list, you remember a walk through a place you already know cold, with a vivid image waiting at each stop.
How to build a memory palace, step by step
-
Choose a route you know well. Your home is the classic choice. Fix a clear path through it: front door, hallway, kitchen, sofa, and so on. The order must be consistent every time.
-
Pick your stops (loci). Settle on specific spots along the route, maybe eight to ten to start. Front door, coat hook, kitchen sink, fridge. Always walk them in the same direction.
-
Turn each item into a vivid image. To remember “milk,” don’t picture a carton. Picture a flood of milk pouring down your hallway. Strange, exaggerated, moving images stick; plain ones fade.
-
Place one image at each stop. Walk your route in your mind and “leave” each image where it belongs. See it interacting with the location: the milk soaking the doormat, the next item wedged in the coat hook.
-
Walk the route to recall. When you need the list, take the mental walk. Each stop hands you back its image, in order. The route keeps everything sequenced automatically.
A worked example
Say you need eggs, batteries, and a birthday card. Front door: a giant egg cracks open as you enter, yolk everywhere. Coat hook: batteries dangling like heavy fruit, pulling the hook off the wall. Kitchen sink: an enormous birthday card floating in the basin, singing. Absurd on purpose. You’ll still recall them tomorrow.
Practice and measure
Start with a short list and one route. Once it feels natural, build a second palace for a different topic so images don’t collide. Test the effect: take the sequence memory test or the visual memory test before and after a few weeks of loci practice, and compare your result with the average sequence memory score. For an interactive version, use the memory palace builder. To understand the spatial memory this relies on, read types of memory.
Frequently asked questions
Is the method of loci the same as a memory palace?
Yes, they’re two names for the same technique. “Method of loci” is the classical Latin-derived term (“loci” means places). “Memory palace” is the popular name, made famous by the Sherlock Holmes stories and memory competitions. Both describe placing images along a familiar route to recall them in order.
How long does it take to learn the method of loci?
You can memorize a short list on your first try. Making it feel natural takes a few practice sessions over a week or two. The images come faster and stick better with repetition. Competitors spend months refining multiple palaces, but a beginner sees real results almost immediately.
What should I use as my memory palace?
Any place you know extremely well and can picture without effort. Your home is the standard starting point. A commute, an old school, or a familiar shop also work. The key is a consistent route with clear, ordered stops. Once one palace fills up, build another for a different topic.
Does the method of loci work for numbers and studying?
Yes, with a small extra step. For numbers, first convert digits into images using a system like number-to-shape or number-to-sound, then place those images in your palace. For studying, turn key facts into vivid scenes along your route. It works for anything you can picture and want in order.
