Palaestra at Olympia
It is north of the gymnasion. It is square. Its sides are each about 66 meters long. Its door is in the northwest corner. The lower part of the outer walls were made of stone and the upper part of brick. Inside was a sand-covered yard open to the sky. This yard was surrounded on all four sides with colonnades of Doric columns. In bad weather, the athletes practiced under these colonnades.
