Ancient Theatre in Gythio

 The ancient theatre of Gythio is located in the northern part of the city, at the foot of the acropolis. It was built in the early Roman times (2nd century AD) and was excavated in 1891 by archaeologist Andreas Skias. The English School of Archeology continued his work. The hollow of the theatre consists of 15 rows of marble seats, of which the first six, part of the seventh and eighth and part of the orchestra, are preserved in good condition (the hollow of which was 75 meters in diameter). There is a well in the centre of the orchestra that dates back to later times. The first set of seats, designed for officials (known as the Presidency), has seatbacks, which are special backrests. The theatre, which does not have a perimeter corridor and an upper tier, was made of domestic off-white marble, except for the tuffa retaining walls in the north and south sections of the hollow. The stage was 12 meters long and 5 meters wide.

Every summer, the Festival of the Municipality of Gythio, known as the "Marathonissia", occurs on-site. The Festival was established in the late 1950s. It lasts for about a month with theatrical performances, concerts and dance events.
