The name Slangenburg has nothing to do with snakes, but with the Slingebeek stream that meanders through the landscape here. It was once called the "Slingeburcht," but over time, this was corrupted to Slangenburg. Thus, the estate bears the name of the stream that has been winding its way through here for centuries.

The country estate is located near the German border and has a history that dates back to the fifteenth century. Today's country estate (house and park) was created at the beginning of the 19th century. Landfort is a so-called complex historical country estate in which a monumental house with outbuildings forms a unit with a surrounding park, garden or forest

Slangenburg was first mentioned in 1354 as the property of Maes (Thomas) van Baer. In 1585 it was destroyed by the troops of the States General and could only be rebuilt during the Twelve Years' Truce

The Aspel house is located about 3,000 meters northeast of Rees-Haldern and is considered an example of castle and palace history spanning more than a thousand years. A stone castle was built in the 12th century from an earth mound castle (motte type) built around 950. This castle became a moated castle almost 500 years later under Prussian influence in the 17th century. Visible today is a baroque, two-wing palace complex on the site of the former outer bailey. The builder of the first stone castle was Count Palatine Richzio. Other owners: Archbishops of Cologne, the von Wittenhorst - Sonsfeld family (after 1686) and the congregation of the "Daughters of the Holy Cross" (since 1850). In 1850, the order "Daughters of the Holy Cross" from Liège (Belgium) bought the manor house. They followed a call to the hospital in the city of Rees. A monastery, novitiate and lyceum were set up in the castle. During World War II the castle was badly damaged by bombs and shells. After the war ended, it served as a military hospital and hospital before the school was reopened in 1946. In 1972 the monastery and school were separated. Today the Spiritual Center of the Daughters of the Holy Cross is located there, a place of silence, prayer and encounters. After almost 172 years, the story of the Daughters of the Holy Cross in Haus Aspel in Rees-Haldern will come to an end in 2022.

After extensive renovation, it is now open for tours.

A number of historical buildings can still be seen in the city.

Good news, May 2024 update: starting with Pentecost weekend, the cafés and restaurants at the coach house will be open again on weekends. The castle can also be visited on weekends – tickets and more information are available at https://www.kasteelslangenburg.nl/. You can also still visit 't Onland (https://hetonland.nl/). Taverne Edelweiss closed on October 1, 2025. I don't know if new owners will be taking over, and if so, when.

If you are in the town of `s Heerenberg, you should definitely go to the dam around Haus Bergh, from there you can take great photos of the fortress.
