In a canyon, in 340 BC, an Argos architect Polykleitos the Younger, built, according to Pausanias, the theatre of Epidaurus. Among all the ancient theatres, Epidaurus theatre is the most beautiful and best preserved. Destined for the fun of the patients of Asklipieio, it had a capacity of 13,000 spectators. It was divided into two parts: A 21-rows of seats part, aimed for the citizens and a 34-rows of seats part aimed for the priests and rulers. The superb acoustics as well as the very well preserved construction, contributed to the creation of Epidaurus Festival S.A., an institution that contributed to the cultural revival of the theatre. Great actors have acted at such as Alexis Minotis, Thanos Kotsopoulos, Anna Synodinou, Thanasis Vengos and the famous Greek soprano Maria Kallas.

Excavations and buildings
The excavations at Epidaurus were executed by P. Kavadias and lasted from 1881 until his death. The excavations were undertaken by the Archaeological Society. Important role in the course of the excavations was the selfless offer of the residents of Lygourio, who, apart from their help, offered their land located near the archaeological site. The first area that the visitor faces upon reaching the archaeological site is the entrance. The entrance, which construction dates back to the Mycenaean times, consisted of two galleries with 6 columns each, built in Ionian and Corinthian type. The second building is the temple of Asclepius, which construction lasted for 5 years. It was a Doric temple where Asclepius statue was hosted. The statue was made by Thrasymedes from Paros Island. Behind the temple there was the dome, which was the most famous building of the sanctuary. Other buildings were the house of priests, the temples to Artemis, the temple of Apollo and finally the theatre.

The small theater of Ancient Epidavros was established in the Acropolis of the ancient city of Epidavros at the South-Western slope, before the period of Asklepios.

It was used mainly for the events of the Dionysian cult, so it was dedicated to the god Dionysus. From the dedicatory inscriptions, it can be concluded that the construction of the theatre was held during the 4th cent., with the sponsorship of prominent rulers and upper class people. A remarkable characteristic of the theatre are the inscriptions, which consist a real – living museum. This is why it is called “the theatre that speaks”. After 23 centuries of silence, the excavation began in 1971. Every July, significant musical and theatrical events take place in this small theatre. The most important is the program “Musical July”.

The Castle in Nea Epidavros is an important attraction which came to the possession of Venice in 1205, after the Byzantine period when its walls were reinforced.

During the period between 20th December 1821 and 16th January 1822, the First National Assembly of the Greeks took place at Piada.

59 representatives from most of the rebellious areas attended the Assembly and voted for the proclamation of the First Assembly, while they appointed the blue and white colours of the Greek flag.

The Citadel of Kazarmas is a relatively small fortification and is located on the ancient road Argos – Nafplion – Epidaurus.

Was constructed probably by the Citizens and was obviously on the border of ancient cities – States of Argos and Epidaurus. The Citadel of the Kazarma (85m. x 75 m.) is located in the 15th kilometer of public road Nafplion – Epidaurus, and is built on a hill of height 28 m. The walls (2.50 m width and height 5.20 m) is made with polygonal system and probably date back to the 4th century BC. The Citadel has four circular towers. The main entrance is to the West and a gate there is in the East. Has rebuilt during the Byzantine era.

Visitors can visit the Acropolis of kazarma from the eastern side of the Hill, where a road has been constructed. There have been excavations and space configuration tasks.
