[3] When Robert Rochfort decided to use Belvedere as his principal residence, he employed French stuccatore Barthelemij Cramillion, to execute the Rococo plasterwork ceilings.

The house was initially built by Robert Rochfort as a retreat, having incarcerated his wife in their previous home at Gaulstown, for an alleged affair with his brother Arthur.

Robert built The Jealous Wall after falling out with his brother George, who lived on the adjacent estate at Tudenham.

Charles moved into the house and during his time there was responsible for the alteration of the Diocletian windows on the upper façade and for the addition of the terracing.

In the period following the second world war, Charles Howard-Bury, who was a soldier and mountaineer, restored the house and gardens.
