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 Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
