The Castlewellan National Arboretum and the Annesley Gardens are of national importance and should be of Heritage garden status.
They contain 42 Champion trees and 20 of the oldest specimen trees in the British Isles. The Annesley Gardens date from 1742 and contain many rare plants. The herbaceous borders were some of the best I have visited.
The glass houses are now probably beyond repair and the borders are being choked with weeds. Some of the rare shrubs are deteriorating. In the Republic many estate gardens have been restored and attract many tourists. It is sad existing tourist attractions here are allowed to deteriorate.
Castlewellan Forest Park is also home of the Peace Maze, the longest hedge maze in Europe, but one could be in the car park and unaware of its existence a few yards away.
