The Ancient Greek Theatre of Gitanae was built in the mid-3rd century BC, a time of increased building activity in Epirus, and destroyed by the Romans in 167 BC.

The theatre is built on the lower level of the settlement, outside the walls, and is protected by a rampart.

It seems that the theatre was originally built in stone, mainly using white limestone. The orchestra forms a full circle which contains an inscribed square and is intersected by the proscenium.

The cavea consists of 28 tiers of seats with two passageways, while there may also have been an amphitheatre.

The theatre seats are made of carefully-dressed limestone, and many bears incised inscriptions with names on the front side.

The stage is a rectangular stone building measuring 15.50m x 5.50m. Inside it was discovered a colonnade consisting of seven rectangular pillars, which would have supported the roof of the stage building.

In the centre of the stage is a doorway through which the actors would have entered, while the floor is made of rubble and beaten earth.

The façade of the stage forms a proscenium whose stylobate (base) is preserved to a length of 15.50 m. and an average width of 0.50 m. There were square parascenia on either side of the stage.
