Lews Castle was built in the years 1847-1857 as a country house for Sir James Matheson who had bought the whole island a few years previously with his fortune from the Chinese Opium trade. It was designed by the Glasgow architect Charles Wilson.
In 1918, the Lewis estate including the castle was bought by industrialist Lord Leverhulme from the Matheson family. He gave the castle to the people of Stornoway parish in 1923.
During World War II the Castle was taken over as accommodation for air and ground crew of 700 Naval Air Squadron, who operated a detachment of six Supermarine Walrus aircraft from a slipway at Cuddy Point in the Grounds. The base was referred to as HMS Mentor.
After the war, the Castle was also used for accommodation for students of Lews Castle College in the 1950s.References:
Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. 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.
