Overview
Castlewellan is a small, vibrant town in south‑east County Down, set against the backdrop of the Mourne Mountains and the tranquil waters of Castlewellan Lake. Designed in the 19th century by a French architect for the Annesley family, the town is laid out around two tree‑lined squares – the upper square hosts the 1764 Old Market House, now a public library, while the lower square is framed by chestnut trees that burst into blossom each spring. Beyond the streets, the crown jewel is Castlewellan Forest Park, a 460‑hectare landscaped estate that houses a Scottish‑baronial castle, the National Arboretum of Northern Ireland, the world‑renowned Peace Maze and a 40‑hectare lake.
History & Background
The Castlewellan area bears traces of ancient settlement, including the early‑Christian Drumena Cashel with its souterrain and the nearby Legannany and Goward dolmens. In the mid‑18th century the Annesley family acquired the demesne and began shaping it into a grand estate. The 5th Earl, Hugh Annesley, started the arboretum in 1740, eventually introducing over 1 800 species of trees and shrubs; more than 700 taxa survive today, including at least 30 champion specimens and a rare giant sequoia grown from 1856 California seed.
The centerpiece, Castlewellan Castle, was erected between 1856‑1858 for the 4th Earl Annesley. Designed by Scottish architect William Burn and built from locally quarried granite, the castle displays characteristic towers, turrets and stone‑mullioned windows. After a period of vacancy, it was repurposed in 1974 as a Christian conference centre – a function it retains, though the exterior can be admired from the park’s promenade.
The estate was gifted to the state in 1967 and opened as a public forest park. Restoration work between 2012‑2014 revived historic greenhouses, the Moorish Tower and other features, while a £5.5 million heritage grant in 2021 funded further arboretum and courtyard improvements. In 2000 the community planted the Peace Maze – a 6 000‑yew‑tree hedge symbolising a hopeful path.
