Gilling Castle is a grade I listed castle near Gilling East, North Yorkshire, England (grid reference SE611768).
The castle was originally the home of the Etton family, who appeared there at the end of the 12th century. It was Thomas de Etton who built the fortified manor house in the 14th century – a large tower almost square, whose basement still forms the core of the present building. In 1349 his father had settled the manor of Gilling on his wife's family, the Fairfaxes, in the event of the failure of the Ettons to produce a male heir. Thus, Thomas Fairfax was able to claim the property in 1489, and it was his great-grandson, Sir William Fairfax, who succeeded in 1571, and undertook the rebuilding of the old 14th-century house. Building on top of the medieval walls and leaving the ground floor intact, he rebuilt the first and second floors, adding at the back (east) a staircase turret and an oriel window. The Great Chamber was also built at this time.
At the beginning of the 18th century the owner, now Viscount Fairfax of Emley, remodelled much of the interior of the house and added the wings enclosing the front (west) court. Though this work has often been attributed to John Vanbrugh or James Gibbs, an attribution to the Yorkshire gentleman architect William Wakefield (died 1730), is based on a written note by Francis Drake. Minor alterations were made in the 1750s by John Carr, who was engaged in remodelling the interior of the prominent Fairfax seat in York, Fairfax House, in Castlegate.
On the death of Mrs Barnes (Lavinia Fairfax) in 1885, this branch of the family became extinct and the castle, after passing through several hands, was bought by Ampleforth Abbey in 1929. The vendor, however, retained the panelling and glass of the Great Chamber and sold it separately. The fittings were recovered for Gilling, with the help of the Pilgrim Trust and many friends and subscribers, and restored to its old home in 1952.
