Method of loci

The method of loci (loci being Latin for "places"), also called the memory palace or mind palace technique, is a mnemonic device adopted in ancient Roman and Greek rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero's De Oratore, and Quintilian's Institutio Oratoria). In basic terms, it is a method of memory enhancement which uses visualization to organize and recall information. A lot of memory contest champions claim to use this technique to recall faces, digits, and lists of words. These champions’ successes have little to do with brain structure or intelligence, but more to do with using spatial memory.

The term is most often found in specialised works on psychology, neurobiology, and memory, though it was used in the same general way at least as early as the first half of the nineteenth century in works on rhetoric, logic, and philosophy.John O'Keefe and Lynn Nadel refer to:

The items to be remembered in this mnemonic system are mentally associated with specific physical locations. The method relies on memorized spatial relationships to establish, order, and recollect memorial content. It is also known as the "Journey Method," used for storing lists of related items, or the "Roman Room" technique, which is most effective for storing unrelated information.
