The splendid edifice of Ayton Castle, the caput of the Scottish feudal barony of Ayton, dominates the town and district.
The original castle, a peel tower, had once been a stronghold of the Home family. This castle was captured by the English in 1497. The tower was replaced by a classical mansion, which burnt down in 1834.
The estate was subsequently purchased by William Mitchell of Parsonsgreen, Edinburgh, Chief Cashier of the Royal Bank of Scotland. From 1846 to 1851 James Gillespie Graham was commissioned to build a new castle at Ayton in the Scottish Baronial style in red sandstone. Further additions were made in the later 19th century. The interiors of the 1875 are still largely extant. William's son, Alexander Mitchell-Innes (1811–1886), commissioned James Maitland Wardrop to build Ayton Parish Church, with a 36-metre spire, and stained glass windows by Ballantine & Sons.
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.
