St Leonard's Hill was a large mansion near Clewer in Berkshire.
The house, originally known as Forest Court, was built by Thomas Sandby for Countess Waldegrave in the 1760s.[1] She named it Gloucester Lodge following her marriage to the Duke of Gloucester in 1766.[2]
The house was bought by William Harcourt, 3rd Earl Harcourt in 1781 and, after remaining in the Harcourt family for over a century, it was acquired by Sir Francis Barry, 1st Baronet in 1872.[1] Barry made substantial alterations in the Châteauesque style and renamed it St Leonard's Hill.[3] Following the death of Lady Barry in 1924 the house was largely demolished.[3]
