As early as the 12th century there was a small predecessor castle on the site of a former Roman villa rustica from the 2nd to 4th century in the present village of Welschbillig.
From 1242 to 1299 the fortifications of the castle were significantly strengthened by the Prince-Elector of Trier, Arnold II of Isenburg and, later, the Landesburg was further expanded by his successors. During the so-called Dutch War the castle was destroyed in 1673/74 by troops of the French 'sun king' Louis XIV and from 1889 to 1891 the southern side was demolished to build a church.
The castle built over the remains of the Roman villa survive today as the remains of a large, quadrangular castle with moats. Still visible are the gateway with its two round towers, a stone bridge over the moat and the remains of the northwest tower.
The Roman villa was built in the shape of the letter 'U' next to a 58.3 by 17.8 metre water basin, which was originally surrounded 112 hermas. 71 of the hermas may be seen in the Rheinisches Landesmuseum Trier.
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.
