Ter Worm or Terworm Castle has existed since the 14th century and has been inhabited by several noble families. Originally it was a square building, fronted by a round tower and a rectangular tower and built around a walled courtyard. The first known owner was the Lord of Strijthagen in 1476, when the castle was a moated building fortified by external walls outside the moat. In 1498 the castle came into possession of the sheriff of Heerlen, Diederick van Pallandt. In 1542, the castle came into the possession of the Van Hallen family, and was destroyed by fire in 1550 but rebuilt in the same style. The rebuilding, completed by the Wijlre family, was done in brick and the building was painted white to disguise the difference in building materials. The castle remained in this family's possession until 1738, when Friedrich Wilhelm Freiherr von Wylre, canon of Aachen, died. His possessions passed to Phillip Anton van der Heyden zu Belderbusch.
In 1767 the castle was restored by Count Maximilian van der Heyden-Belderbusch and the gardens laid out in the French rococo style. In 1840 the castle was inherited by Antoinette von Böselager, who was married to Baron Otto Napoleon Loë-d'Imstenraedt. After her death, the castle came into possession of the baron. His family extended the estate by purchasing many neighbouring farms.
In the late 19th Century the castle and the estate acquired its present appearance thanks to Baron François de Loë, who remodelled it in a neo-Gothic style to the plans of Lambert de Fisenne. Throughout most of the 20th century, the castle and its estate were in the hands of the Orange-Nassau mine, and the castle housed some of their staff. In the castle grounds at that time was a large outdoor swimming pool, in which whole generations of the people of Heerlen learned to swim. After the closure of the mine the government suggested that a major theme park should be founded on the estate, an idea squashed by the people of Heerlen after a large-scale and widely supported protest. In the last decades of the twentieth century the castle became very run down until it was bought by the Van der Valk hotel chain, who restored it in 1997-1999. It is a now a hotel and restaurant.
The present building dates largely from the 17th century when the original 15th-century fortified building was converted into a house. It comprises two wings in a T-shaped floor plan surrounded by a moat. The main building is accessible at the front via a marl stone bridge dating from 1843 leading to the main entrance. Between the two wings is a corner tower, which is the oldest part of the castle dating back to the 15th century. Originally round, the tower was converted to an octagonal in the 17th century . The west wing can be dated to 1716, while the south wing has a keystone with the year 1718. The castle garden is a reconstruction based on a French rococo garden laid out by Count Vincent van der Heyden-Belderbusch in 1787 with roses, lavender and boxwood. The garden is a favourite wedding location and admission is free.References:
Château de Falaise is best known as a castle, where William the Conqueror, the son of Duke Robert of Normandy, was born in about 1028. William went on to conquer England and become king and possession of the castle descended through his heirs until the 13th century when it was captured by King Philip II of France. Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840 it has been protected as a monument historique.
The castle (12th–13th century), which overlooks the town from a high crag, was formerly the seat of the Dukes of Normandy. The construction was started on the site of an earlier castle in 1123 by Henry I of England, with the 'large keep' (grand donjon). Later was added the 'small keep' (petit donjon). The tower built in the first quarter of the 12th century contained a hall, chapel, and a room for the lord, but no small rooms for a complicated household arrangement; in this way, it was similar to towers at Corfe, Norwich, and Portchester, all in England. In 1202 Arthur I, Duke of Brittany was King John of England's nephew, was imprisoned in Falaise castle's keep. According to contemporaneous chronicler Ralph of Coggeshall, John ordered two of his servants to mutilate the duke. Hugh de Burgh was in charge of guarding Arthur and refused to let him be mutilated, but to demoralise Arthur's supporters was to announce his death. The circumstances of Arthur's death are unclear, though he probably died in 1203.
In about 1207, after having conquered Normandy, Philip II Augustus ordered the building of a new cylindrical keep. It was later named the Talbot Tower (Tour Talbot) after the English commander responsible for its repair during the Hundred Years' War. It is a tall round tower, similar design to the towers built at Gisors and the medieval Louvre.Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840, Château de Falaise has been recognised as a monument historique by the French Ministry of Culture.
A programme of restoration was carried out between 1870 and 1874. The castle suffered due to bombardment during the Second World War in the battle for the Falaise pocket in 1944, but the three keeps were unscathed.
