History+
The origins of Haus Hall lie in a medieval moated castle, which served as a fief of the Lords of Heinsberg from at least the 15th century. From the early 16th century, the Olmissen family was the sole owner of the estate for approximately 300 years. Through an heiress, the property later passed to the Spies von Büllesheim family, who remain the owners today. In 1785, the existing Gothic residential building was replaced by a Neoclassical new construction. At the beginning of the 20th century, in 1904, the manor house was extended with two short side wings in the Neo-Baroque style, giving it its current appearance. The entire building complex has been a protected monument since November 11, 1982.
