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:
The famous Italian Medici family have given two queens to France: Catherine, the spouse of Henry II, and Marie, widow of Henry IV, who built the current Luxembourg palace. Maria di Medici had never been happy at the Louvre, still semi-medieval, where the fickle king, did not hesitate to receive his mistresses. The death of Henry IV, assassinated in 1610, left the way open for Marie's project. When she became regent, she was able to give special attention to the construction of an imposing modern residence that would be reminiscent of the Palazzo Pitti and the Boboli Gardens in Florence, where she grew up. The development of the 25-hectare park, which was to serve as a jewel-case for the palace, began immediately.
The architect, Salomon de Brosse, began the work in 1615. Only 16 years later was the palace was completed. Palace of Luxembourg affords a transition between the Renaissance and the Classical period.
In 1750, the Director of the King's Buildings installed in the wing the first public art-gallery in France, in which French and foreign canvases of the royal collections are shown. The Count of Provence and future Louis XVIII, who was living in Petit Luxembourg, had this gallery closed in 1780: leaving to emigrate, he fled from the palace in June 1791.
During the French Revolution the palace was first abandoned and then moved as a national prison. After that it was the seat of the French Directory, and in 1799, the home of the Sénat conservateur and the first residence of Napoleon Bonaparte, as First Consul of the French Republic. The old apartments of Maria di Medici were altered. The floor, which the 80 senators only occupied in 1804, was built in the middle of the present Conference Hall.
Beginning in 1835 the architect Alphonse de Gisors added a new garden wing parallel to the old corps de logis, replicating the look of the original 17th-century facade so precisely that it is difficult to distinguish at first glance the old from the new. The new senate chamber was located in what would have been the courtyard area in-between.
The new wing included a library (bibliothèque) with a cycle of paintings (1845–1847) by Eugène Delacroix. In the 1850s, at the request of Emperor Napoleon III, Gisors created the highly decorated Salle des Conférences, which influenced the nature of subsequent official interiors of the Second Empire, including those of the Palais Garnier.
During the German occupation of Paris (1940–1944), Hermann Göring took over the palace as the headquarters of the Luftwaffe in France, taking for himself a sumptuous suite of rooms to accommodate his visits to the French capital. Since 1958 the Luxembourg palace has been the seat of the French Senate of the Fifth Republic.
