Rossmore Castle
Rossmore Castle, also known as Rossmore Park, stood near Monaghan in County Monaghan, Ireland. Built in 1827 in the Gothic style for the 2nd Baron Rossmore, it was designed by architect William Vitruvius Morrison. The house was dominated by a large square tower with a turret, crow-stepped battlements, and it had many gables and oriel windows. It was extended and remodelled in 1858 by William Henry Lynn.
A rivalry with the Shirleys of Lough Fea led to a famously large drawing room; the room was extended five times, and the house ended up with three towers and more than 117 windows of many sizes.
In its later years the castle was famous for social gatherings, and the 5th Baron Rossmore was a friend of Albert Edward, Prince of Wales. The 5th Baron served as Lord Lieutenant of Monaghan from 1897 to 1921, and his son William became the 6th Baron.
After World War II, dry rot forced the family to abandon the castle and move to Camla Vale, a smaller Georgian house on the estate. The castle fell into ruins and was demolished in 1975. Camla Vale was sold in 1962 and later demolished.
In 2021, Paddy Rossmore died and left 2,200 acres of the Rossmore estate to An Taisce, the national trust.
