The settlement of Heusden, bordering on the river Meuse (Maas), as we know it today dates back to the 13th century, and started with the construction of a fortification to replace the castle that was destroyed by the Duke of Brabant in 1202. This fortification was quickly expanded with water works and a donjon (castle keep). The city of Heusden received city rights in 1318. The castle of Heusden was the property of successive dukes of Brabant, in 1357 it went over to the counts of Holland.
With the construction of ramparts and moats the castle became located within the city's fortifications, and the castle lost its function as a stronghold. The donjon was now used as a munition depot. A disaster marked the end of the castle of Heusden and caused the economic demise of the city; on 24 July 1680 a terrible thunderstorm hit Heusden, and lightning struck the donjon. Sixty thousand pounds of gunpowder and other ammunition exploded, and destroyed the castle. It took the people of Heusden seven weeks to clear the rubble and debris. The castle was never fully rebuilt. However, the original outlines of the main features were restored in 1987.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.
