Rossmore Castle

Rossmore Castle was a large country house distinguished by three towers of varying designs: a square tower with a turret, a polygonal tower with a cupola, and another square tower with a spire. The different building phases resulted in a mixture of architectural styles across the structure.

The castle was designed in 1827 by William Vitruvius Morrison in Tudor Gothic style for the 3rd Lord Rossmore. Architect William Henry Lynn added a Scottish Baronial wing in 1858, significantly reshaping the building's appearance.

The residence reflected the architectural evolution of Irish country houses through its combination of Tudor Gothic and Scottish Baronial design elements.

The building survives today as ruins and can be viewed from outside, though the structure is partially deteriorated in places and visitors should expect uneven ground. It is best visited during daylight hours and visitors should wear appropriate footwear for walking over rough terrain.

The castle contained 117 windows in 53 different shapes and sizes, a result of multiple expansions. This unusual collection came from a competition among residents over who could have the largest room in the county.
