Gardie House is an 18th-century estate house, unique in Shetland. The Henderson family owned Gardie from the 17th century, and in 1724 Magnus Henderson (died 1753) had the present house built. The builder was a mason from Aberdeen named Forbes. The double-pile plan of Gardie was relatively novel in the early 18th century. The symmetrical arrangement of walled gardens leading down to a harbour was laid out at the same time. The drawing room contains fine wooden panelling, installed around 1750.
The house passed out of the Henderson family in 1799, and was inherited by Elizabeth Nicolson and her husband Thomas Mouat of Garth, the builder of Belmont House on Unst. Their nephew, William Mouat, added the porch and constructed the steading and Gothic cottage in the grounds. Sir Walter Scott dined at Gardie House during his 1814 visit to Shetland. In 1905 the house was altered, and remains privately owned. In 2001, the owner was John Hamilton Scott, Lord Lieutenant of Shetland.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
