Duivenvoorde Castle was first mentioned in 1226, making it one of the oldest castles in South Holland. The castle is remarkable in that it has never been sold, which can be said of very few Dutch castles. It has passed by inheritance through several noble houses, sometimes through the matrilineal line. For the first five centuries of its history, the castle was owned by one family, the van Duivenvoordes, who gave their name to it. Although thus named, the van Duvenvoirdes properly formed part of the House of Wassenaer, an ancient noble family which has played an important role in Dutch history. Towards the end of the 17th century an owner of Duivenvoorde Castle, Johan van Duvenvoirde, readopted the name of van Wassenaer. Therefore, although the same family remained in the House, this was under a different name.
The last private owner of the castle was Jonkvrouwe Ludolphine Henriette, Baroness Schimmelpenninck van der Oye (1891-1965). Knowing that with her death the house would be sold and the furniture dispersed, including the collections of portraits, porcelain and clothing and textiles, she decided to close the house and leave it in the care of a foundation for restoration. The stated aim was to restore the castle to its appearance in 1717, although in practice this has not always been possible. The terrace constructed around 1844 has been kept, and the opening of previously sealed windows to allow more light into the living room has taken away some symmetry. The interior has been redecorated to match the colours of 1717, and later piecemeal work on the ceilings has been left in place. Today Duivenvoorde is a musem.
In 1717, two Roman stones were installed as plaques in the front hall. The larger of the two stones, dated between 196 and 198 AD, has an inscription on the front about the repair of an armory by Roman troops; the text on the other side is older, dating from somewhere between 103 and 111 AD. In the making of the newer text, the stone was made smaller, damaging the older text. The smaller stone has a text which, through knowledge of the people named there in, can date the stone to around 205 AD.
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 Šaloun 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.
