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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
