Heisdorf Castle was built by Baron Lippmann in the late 19th century. Surrounded by a large park, it was designed by the Belgian architect Charles Thirion. In 1916, the Sisters of the Christian Doctrine acquired the property as a convalescent home for their community. In 1982, it was opened as an old people's home under the name of Maison de retraite Marie-Consolatrice. In 2007, a new wing was added to the building by the architecture firm Hermann, Valentiny and Partners providing improved facilities for its senior citizens.
The castle consists of two wings at a right angle to one another. The main entrance is in the middle of the building, in the square tower which connects the two wings. The end of the wing on the Alzette side consists of a round tower with a roof in form of a cupola, with a spire above it. This tower contains the knights' hall. From the outside, a monumental stairway leads to the first floor of the tower. Above the main entrance, one can see the years 1645 and 1888. The present castle was built in 1888, on the location where Jean de Beck had built a previous castle in 1645. The castle includes a chapel, which was built by the Sisters in 1924, on the side of the main street, where the two wings are connected. The chapel was built in 1924 and renovated in 2005-2006.
The castle grounds include a large park, along the main road, from which it is separated by a high wall. The park was renovated after 1910, which left the old trees standing. Two of these, a black pine and an oak tree, are counted among the 'notable trees' of Luxembourg.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.
