This monumental masterpiece of the City has a capacity for 20,000 spectators and its stage is just like a many-storied apartment. The doors in the walls are outlets for the actors in order that they might change their attires. There used to be tiers on the right as balconies and on the left too. The right tiers belonged to the Emperor. It was restored in the Seljuk Dynasty and used as a palace. The walls were embellished with china-work (tiles). The sitting places for spectators were separated from the stage by a strolling space (Diazoma). The gallery on the upper part has been added later.
