Gylen Castle was built in 1582 by the Clan MacDougall. Gylen was only occupied for a relatively short period of time. The castle was besieged then burned by the Covenanters under General Leslie in 1647 during the Wars of the Three Kingdoms.
In May 2006 a restoration of the castle was completed with a £300,000 grant by Historic Scotland and £200,000 raised by worldwide members of Clan MacDougall.

It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
