The castle in Stapelen was first time mentioned in 1293 when it was donated to Willem I van Boxtel. Hendrik Mahie restored the castle in the 19th century to the current Neo-Gothic appearance. The oldest parts of the castle, like the octagonal tower, date from the Middle Ages and the walls from the 16th century. The chapel has a altar from the 17th century. Today Stapelen castle is a monastery.References:
The Walhalla is a hall of fame that honors laudable and distinguished people in German history. The hall is a neo-classical building above the Danube River. The Walhalla is named for the Valhalla of Norse mythology. It was conceived in 1807 by Crown Prince Ludwig in order to support the then-gathering momentum for the unification of the many German states. Following his accession to the throne of Bavaria, construction took place between 1830 and 1842 under the supervision of the architect Leo von Klenze.
The memorial displays some 65 plaques and 130 busts covering 2,000 years of history, beginning with Arminius, victor at the Battle of the Teutoburg Forest in 9 AD.
