The tower of St Patrick's Church, Ireland's first Protestant church, dates from 1578. The neighboring Cathedral (RC) is neo-Gothic.
Castlewellan (pop. 2,100) is a small market town. It contains a Forest Park which features a three mile trail around the lake where visitors can view sculptures carved from the park's natural minerals. Queen Anne-style courtyards, tropical birds. This national arboretum was founded in 1740.
