Upper Court
In 170 AD, the Telesterion was burnt down by the Cotsoboci, invaders of northern origin. In its reconstruction, in the years of emperor Marcus Aurelius (121-180 AD), the plan of the classical times was kept, with an extension of about two metres to the north.
In Roman times, moreover, two stairs were cut in the rock that led to an elongated square, 70m long and 11,45m wide (Upper Court), which was created by levelling the rock along the west side.
