The Sassenpoort is a gatehouse in the citywall of Zwolle, Netherlands. It was build in 1409 after Zwolle city became a member of the Hanseatic League in 1407. The city gates represent the wealth of this period. In the period between 1893 and 1898 restoration work took place. The dormers were made, and a neogothic spire clock tower was installed, replacing an earlier 18th century spire. In between the corner towers is a machicolation. From holes in the floor of this outer work, boiling oil could be thrown at enemies. The gatehouse is a rijksmonument since 1967 and is part of the Top 100 Dutch heritage sites. The gate now serves as a pedestrian road.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.
