The Admiralty Church (Amiralitetskyrkan), also known as the Ulrica Pia, was inaugurated in 1685. It is made entirely of wood, making it Sweden's largest wooden church. Originally it could seat 4,000.
The interior is in a light bluish color while the exterior is in the traditional Falu red. Its shape is a squarish greek cross, with each cross arm measuring 20 metres. In front of the main entrance stands the wooden figure of Rosenbom. The church is part of the UNESCO World Heritage Site Karlskrona naval base since 1998.
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.
