Söderby-Karl Church was built around 1300 or soon later. The porch was added later in the 1300s and brick arches in the mid-1400s. The external bell tower was erected probably in 1664. The main restoration was done in 1790. The interior is decorated with beautiful murals from the late Middle Ages which have never been overpainted. The sandstone font dates from 1200s.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.
