St Tugual's Chapel dates back to the 11th century when the island was a haven for an order of Norman monks. However, there is evidence that the site has had religious significance since the 6th century. The chapel was designed in such a way that they could sit in the building's north nave without being seen by the public who would sit in the west portion of the chapel.
In the years before the Wood family took hold of the lease on the island, in 1949, the grounds around the west and south of the chapel had become overgrown and it was in their time that the churchyard come garden was made around the church.

Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
