PUBLIC NOTICE: Newry, Mourne and Down District Council is undertaking restoration works in the Annesley Gardens in Castlewellan Forest Park as part of ‘Re-Rooting our past in the Future: Castlewellan Historic Demesne’, project part funded by The National Lottery Heritage Fund.  The works will revitalise and conserve the natural heritage of the gardens for present and future generations. Please note that the Walled Garden is closed to facilitate restoration works to the paths and fountains. We apologise for any disappointment this causes.

The planting of the walled Annesley Garden, the focus of the arboretum, begun in the 1850s and rare conifers and maples were later imported directly from Japan. Then came the addition of more rich varieties, including Chilean eucryphias, Australian athrotaxis and pittosporum and Chinese rhododendrons. The arboretum holds many trees with record heights in the British Isles.
