The gymnasium in Ancient Greece functioned as a training facility for competitors in public games. It was also a place for socializing and engaging in intellectual pursuits. The name comes from the Ancient Greek term gymnós, meaning "naked" or "nude". Only adult male citizens were allowed to use the gymnasia.

A palaestra was any site of an ancient Greek wrestling school. Events requiring little space, such as boxing and wrestling, took place there. Palaestrae functioned both independently and as a part of public gymnasia; a palaestra could exist without a gymnasium, but no gymnasium existed without a palaestra.
