Rossmore Castle

The story of the great castle that once stood at the heart of the Rossmore estate in County Monaghan.

Rossmore Castle, County Monaghan

Rossmore Castle was once the magnificent centrepiece of the Rossmore estate, the landscape that today forms Rossmore Forest Park near Monaghan town. Although the castle itself no longer stands, its story remains an important part of the history and character of the park.

Visitors exploring Rossmore today can still discover surviving remains and estate features that provide a glimpse into the period when the grounds were home to the Rossmore family and formed part of a large country estate.

The Rossmore Estate

A Grand Country Estate

The castle stood within an extensive landscaped estate of woodland, lakes, gardens and estate buildings. Many features associated with this historic landscape can still be found throughout Rossmore Forest Park.

The Westenra Family

Rossmore Castle became closely associated with the Westenra family, the Barons Rossmore. Their story is woven into the history of the estate and into surviving features such as the Rossmore Mausoleum.

What Remains Today?

The loss of the castle did not erase the history of Rossmore. Traces of the old estate survive throughout the forest, allowing visitors to explore a landscape shaped by generations of estate life.
