Belvedere House and Gardens
A lakeside villa with follies including a huge sham ruin built purely to block the view of a hated brother's house.
Updated 19 October 2026
Belvedere was built around 1740 for Robert Rochfort, later Earl of Belvedere, and its follies record a spectacularly poisonous family history. Rochfort accused his wife Mary of an affair with his younger brother Arthur, sued Arthur into ruin and prison, and kept Mary confined at Gaulston for over thirty years - she was released only after her husband died. When another brother, George, built a fine house nearby, Rochfort had a vast Gothic sham ruin erected across the sightline so he would not have to look at it; it is called the Jealous Wall, it is the largest folly in Ireland, and it still stands. The house itself is small for its status, a compact villa by Richard Cassels with fine rococo plasterwork, set above Lough Ennell. The estate covers about 65 hectares with a walled garden, terraces, woodland trails and other follies. It is a family destination now, with a playground and cafe.
History
The house was built in 1740 as a hunting lodge for Robert Rochfort, 1st Earl of Belvedere, by the architect Richard Cassels, and the French stuccatore Barthelemij Cramillion made its Rococo ceilings. Rochfort built it as a retreat after confining his wife at their earlier home, Gaulstown, over an alleged affair with his brother Arthur, who was fined £20,000 he could not pay and spent 18 years in a debtors' prison (Wikipedia, Belvedere House and Gardens).
