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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
