The Church of the Holy Trinity (Heliga Trefaldighets Kyrka) was built in the 13th century; the earliest plans were of a monastery for an order of Franciscan monks which had settled in Arboga. Early in the 16th century Gustav Vasa started Reformation in Sweden and the monastery was opened as a church for the people of Arboga.
During renovations in the 17th century a church tower was added to the building. Among the artifacts of the church is the pulpit from 1736, beautifully carved by the royal sculptor Buchard Precht. The light fittings in brass are believed to be the largest in Sweden, possibly the whole of Scandinavia. 13th century murals are displayed on the south wall, including a depiction of the life of Saint Francis.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.
