The castle of Monschau was probably built at the beginning of the 13th century. In the middle of the 14th century, the complex was extended and enclosed by mighty ring walls and ramparts. This almost impregnable fortress of the Counts of Jülich was besieged by Emperor Charles V in 1543 with heavy artillery and finally captured, the city was sacked. The castle was only restored to expand the weather complex of the lower castle. The Frenchmen confiscated the castle as a national asset and sold it. However, the private owners were unable to maintain the extensive complex. They had the roofs demolished in 1836/37 in order to be freed from the tax on buildings. The castle quickly fell into ruins. It was not until the turn of the century that the province tried to stop the decline. The castle was secured, repaired and renovated. After the First World War, a youth hostel occupied the west wing. The castle of Monschau as a "youth castle" thus remains lively and inviting. Christo even packed it in 1971, and it is a highlight of Monschau when the castle and town are lit up. In summer, the inner courtyard of the castle becomes the atmospheric backdrop for the "Monschau Festival". Then the performances of renowned artists and renowned orchestras transform the fortress into a real Mecca for music fans. There is a youth hostel in the castle. Unfortunately, for this reason, the building cannot be visited. But a visit to the courtyard and the fantastic view of the city are also worth it!
