Heemstede castle was first built in 1280 by Dirk van Hoylede from the region of Vlaardingen. Built, burned and rebuilt over the centuries, it was last torn down in 1810, after years of neglect. The monumental gatekeeper's house 'Nederhuys', built in 1630 remains intact as well as the foundations from the Middle Ages. The most famous owner of the castle was Adriaan Pauw, who bought it in 1620. He played a role in the Treaty of Munster, and built the bridge Pons Pacis to commemorate the peace treaty.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.
