Buschfeld Castle (Liblar)

In Liblar, North Rhine-Westphalia, lies Buschfeld Castle, also known as Haus Buschfeld. The complex evolved from a fortified moated castle to a late Baroque palace. It is one of the oldest fortified moated castles in the Rhein-Erft district and was once a knight's seat.
History+
The first documented mention of the estate dates back to 1170, associated with Knight Wilhelm Schilling von Buschfeld. In 1276, Buschfeld Castle became the property of Wennemar von Gymnich. In 1337, Arnold von Buschfeld sold the right of access to the “castrum Buschfeld” to the Archbishop of Cologne. Knight Everhardt von Quadt acquired the complex in 1448, and it remained in the possession of the Quadt family for over 300 years. After the collapse of the so-called Black Tower of the core castle in 1705 and its complete demolition in 1711, Hugo Damian Adolf von Quadt zu Buschfeld had a new manor house built in the late Baroque style between 1708 and 1711. In the 19th century, the castle changed hands several times before being sold in 1926 to the Kommanditgesellschaft Dr. Wegge and used for agricultural purposes.
