Dating back to the 13th century, the building was used as a monastery where nuns and monks, especially those of distinguished families, stayed there. In the mid 14th century, the monastery officially became a convent where the daughters of noble families stayed. From the 16th to the 18th centuries, the monastery suffered damages due to wars, until it was finally closed down.
The castle dates back to the 14th century and was built by Otte von Holtmühle, whose name it also took. Through the centuries, the castle changed many hands and it was abandoned for many years. Today it is a charming historic castle hotel, the most distinctive characteristic of which is the water-filler moat that exists right in front of it.
The castle was initially built in the 14th century by the Lord of Wassenberg as his hunting lodge. It has since changed many hands and housed various noble families. The castle fell into ruin for many years, until it was remade into the hotel that it is today.
The castle was initially built by a lord and it was surrounded by a moat and firm fortification all around it. In the 16th century, the castle was destroyed in a fire, but was soon rebuilt in the shape it had before. Many counts and barons lived in the castle over the ages, and one of them renovated it in the 19th century according to the Gothic-style of the era, a style it retains until today. During most of the 20th century, the castle was used to house miners, and after a renovation that finished in 1999 it was turned into the hotel that it is today.
The initial castle building dates as far back as the 10th century, but the castle took its shape in the 11th century. The castle housed many different noble families over the centuries. Due to its strategic location, the castle had been a constant target of enemy attacks during wars, and many were the times when it was almost completely destroyed. In the 18th century, after having been destroyed and rebuilt, its then owner renovated it into a Neo-gothic mansion, a style it retains until today. The castle was first opened as a hotel in 1968, but its turbulent owner history didn't stop there, as it again changed hands many times until its current owners purchased it in 2018.
