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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
