To be privately owned
Sonsfeld Castle

In Rees-Haldern in the Kleve district, North Rhine-Westphalia, Germany, is Sonsfeld Castle, known today for its history and the remnants of a Baroque garden. The original castle, whose exact location is now only marked by moat remains, was demolished in the early 18th century. A later built manor house now bears the name of the historic castle.
History+
The first documented mention of Sonsfeld Castle dates back to 1259. In 1368, the estate was owned by Steven von Wittenhorst. Sonsfeld, along with surrounding farming communities, was elevated to a lordship in 1666. The original castle was dismantled in the first half of the 18th century, but a planned new building was never realized.
