Downhill House was a mansion built in the late 18th century for Frederick, 4th Earl of Bristol and Lord Bishop of Derry (popularly known as 'the Earl-Bishop'), at Downhill, County Londonderry. Much of the building was destroyed by fire in 1851 before being rebuilt in the 1870s. It fell into disrepair after the Second World War.[1]
Downhill House is now part of The National Trust property of Downhill Demesne and Mussenden Temple.
