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 Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Ĺ aloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
