Monschau Castle is first recorded in 1217 as castrum in Munjoje by Archbishop Engelbert I of Cologne. It was expanded in the middle of the 14th century into a fortress for the counts of Jülich and equipped with mighty ring walls and wall walks. In 1543 troops of Emperor Charles V besieged the site with heavy guns, captured it and plundered it together with the town of Monschau.
In the early 19th century the French administration declared the castle to be state property and sold it to a private buyer who had the roofs removed in 1836 and 1837 in order to avoid building tax. As a result, the castle fell into ruins until, in the early 20th century, the government of the Rhine province secured and repaired it. After the First World War a youth hostel was opened in the west wing. So Monschau Castle survived as a 'youth castle' (Jugendburg).
Within sight of the castle, on the other side of town, is another fortification, the Haller. It is disputed as to whether it was an outpost of the castle, a detached watchtower or the remains of an older castle site.
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.
