A Memory Palace is an imaginary location in your mind where you can store mnemonic images. It has been used since ancient Rome, and is responsible for some quite incredible memory feats.

Many studies have been conducted to analyze the effectiveness of the Memory Palace technique. It's all based on the scientific fact that your brain and spatial memory perceive space as a kind of image.

The method of loci is also known as the memory journey, memory palace, or mind palace technique. This method 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).
