Fasque, also known as Fasque House or Fasque Castle, is a mansion in Aberdeenshire, Scotland, situated near the village of Fettercairn, in the former county of Kincardineshire.
Fasque was the property of the Ramsays of Balmain, and the present house was completed around 1809, replacing an earlier house. It was purchased in 1829 by Sir John Gladstone, 1st Baronet, father of Thomas Gladstone and William Ewart Gladstone, later Prime Minister of the United Kingdom, who often stayed there. Fasque was a family home of the Gladstones until the 1930s, and was open to the public during the last quarter of the 20th century. In 2010 Fasque House was bought by Fasque House Properties Ltd and restoration work was begun.
