Biljoen estate was first mentioned in 1076. In 1530 Charles, Duke of Guelders, built the first castle and it was rebuilt by Alexander van Spaen (1619–1692) into the present day castle with four equal corner towers. The family Van Spaen rebuilt the castle again in the the 18th century. In 1795 French troops were quartered in the castle. After they left the castle was plundered and the interior largely destroyed. The damage was restored with amongst others ornamental plaster and ceiling paintings.
The estate was originally called Broekerhof, and was a place where taxes were collected. In 1076 it was donated by Henry IV, Holy Roman Emperor to the Sint-Pieter Chapter in Utrecht. In 1530 it was sold to Charles, Duke of Guelders. He in turn had to sell it again in 1535 because of debts. It came into possession of Charles' general Roelof van Lennep. Roelof's son Carl, mayor of Arnhem, inherited it in 1546. His son Roelof inherited it in turn in 1567. After family divisions it was sold to the baronial family Van Spaen in 1661. In 1849 baron Van Hardenbroek allowed Anna Pavlovna of Russia to use it temporarily. In 1872 it was inherited by the family Lüps, until 2008.
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.
