Most 18th-century estate follies were built for whimsy. You wanted your parkland to have a focal point, so you commissioned a hermitage, or a temple, or a sham castle on a distant hill. Follies were Georgian Instagram — set dressing for a cultivated view of the world.
The Jealous Wall at Belvedere House is a folly built for none of those reasons. It was built to hide a view. Specifically, to hide one brother's house from another brother's sight.
Three Brothers, One Very Angry Family
Robert Rochfort inherited his title in 1731, aged 23. By 1740 he'd commissioned Belvedere House itself. By 1743 he had imprisoned his wife Mary on a charge of infidelity with his younger brother Arthur, sued Arthur into debtor's prison, and dispossessed Arthur's nine children.
That still left his older brother, George. George owned Rochfort House (later renamed Tudenham House), a larger property than Belvedere, and inconveniently close by. From portions of the Belvedere grounds, George's house was visible on the horizon.
Robert and George had quarrelled — the sources differ on exactly why, but extended family, inheritance politics and the general aura of Rochfort family drama all played a role. What we know is that, around 1760, Robert decided he could not tolerate the sight of his brother's house.
The Solution Most Aristocrats Wouldn't Try
You or I might plant trees. That was, in fact, the standard 18th-century solution to an offending sightline. You could also re-landscape the approach, redirect a walking path, or simply stop walking to the part of the estate that faced the unwanted view.
Robert Rochfort chose none of these. He chose to build a wall. A very specific kind of wall.
The wall was to be three storeys tall. It was to be wide enough to block the entire sightline to Tudenham House. And it was to be designed to look exactly like the last surviving wall of a ruined medieval abbey.
In 1760 that was an expensive, extravagantly pointed gesture. It required master stonemasons. It required imported cut stone for the Gothic window tracery. It required foundations strong enough to support a structure that looked deliberately ruined but was, in fact, new-built and load-bearing.
Why "Jealous" Wall?
The name arrived later, through local tradition. By the 19th century, Westmeath locals had long told the story of why the wall existed — Robert's jealousy of George, Robert's jealousy of his own wife, Robert's jealousy of anyone who seemed to have what he wanted. "Jealous" was the shorthand.
The name stuck because it's accurate. The wall exists because the Earl was jealous. That's its entire functional purpose.
The Wall Outlasted Everyone
Robert Rochfort died in 1774 — possibly murdered, possibly an accidental fall. His brother George had died in 1761, only a year after the wall went up; George never lived to see Robert's descendants eventually reconcile. Mary Rochfort survived her husband, was released from imprisonment, and died in 1791.
Arthur Rochfort eventually rebuilt a life after his imprisonment. Tudenham House — the house Robert couldn't stand to see — declined over the 19th century as the Rochfort family fortunes faded. It's now an actual ruin, not a fake one.
The Jealous Wall is still standing. Restored by Westmeath County Council, paid for in part by Fáilte Ireland and EU conservation funding, it remains the largest folly in Ireland — and almost certainly the only major folly in Europe built as an explicit gesture of sibling hatred.
Visiting the Wall Today
The Jealous Wall is one of the first things visitors see on the Belvedere estate. It's a 10-minute walk from the Visitor Services Centre along clearly marked paths. It's free to photograph. It's approximately 3 storeys tall and can be photographed from ground level, from the side, or through its own window openings. Our dedicated Jealous Wall page has photography tips and exact location.
