The abbatial complex of the Saint Eufemia was founded by Robert Guiscard in the second half of the 11th century in the place of an ancient Byzantine monastery. Present archaeological investigations concern the church, with the focus on the area of the great presbytery and the main apse. In this part, 3-4 m deeper than the ground level (that has risen in time due to the frequent floods of the Bagni river) a polychromatic tessellated marble pavement decorated with geometric patterns of Norman origins was located. In the same site, the outer walls and the pillars supporting the barrel roof were also discovered. The remains of the altar, deprived of marble covering, stand on a raised marble rectangular tribune, in the center of the apse. The semicircular part of the main apse lies under the local road passing near the church.
References:The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
