Castlewellan, County Down, Northern Ireland, is a place where mountains meet the sea and human creativity intertwines with ancient landscapes. At its heart lies Castlewellan Forest Park, a living museum of global flora boasting towering Chilean eucryphias, Japanese maples, and rare conifers that have graced these slopes since 1740. The park's crown jewel, the Peace Maze - a labyrinth of 6,000 yew trees - embodies Northern Ireland's journey toward unity, planted by community members with input from thousands of schoolchildren. Navigate its two-mile hedges to reach a central bell, where visitors can literally ring in understanding amid life's twists and turns.
Step into autumn here, and the trails transform into golden corridors beneath canopies older than the hills they cling to. Families lose themselves in Animal Wood's treehouse forts or paddle kayaks on Castlewellan Lake's glassy surface, while hikers conquer Slievenaslat Mountain for vistas of Strangford Lough stretching to the Mournes' jagged spines. Ancient history lingers too: touch a 5,000-year-old Legannany Dolmen or wander Drumena Cashel's medieval ruins. Whether sipping coffee at Grange Yard's seasonal café or tracing pathways first trodden by Victorian botanists, Castlewellan offers timeless adventures where every turn - literal or metaphorical - is infused with purpose.

History
The history of Castlewellan dates back to ancient times, with evidence of settlement in the area including the Drumena Cashel, a small stone-built farmstead enclosure from the Early Christian period. Nearby, the Legannany Dolmen and Goward Dolmen are megalithic monuments that attest to the region's rich cultural heritage.
In the 18th century, the Annesley family acquired the land from the Maginess family and began to shape the town's layout, with William Annesley planning the tree-lined squares and wide main street in the 1750s. The old market house, built in 1764, still stands today, housing the public library, although its history is also marked by the site of public executions until this practice was outlawed.
The 19th century saw significant developments in Castlewellan, including the extension of the natural lake in Castlewellan Forest Park by the Annesley family and the construction of Castlewellan Castle, a Scottish baronial castle built between 1856 and 1858. The castle was designed by Scottish architect William Burn and commissioned by the 4th Earl Annesley. However, this period was also marked by turmoil, as evidenced by the Dolly's Brae conflict in 1849, which resulted in the deaths of approximately 80 Catholics and the burning of homes.
The town's history is also intertwined with the story of the Annesley family, who enhanced the arboretum and developed the Castlewellan Estate. The estate passed through several generations of the family before being sold to the government. In 1967, the Forest Service of the Department of Agriculture purchased the land and opened the park to the public.
The Troubles had a significant impact on Castlewellan, with incidents such as the killing of three members of the Ulster Defence Regiment in 1980 and the presence of paramilitary groups, including the Provisional Irish Republican Army. The town has historically been an Irish Republican stronghold, with commemorations and marches held to mark significant events, including the 1916 Rising and the 1981 hunger strikes.
In more recent years, Castlewellan has continued to evolve, with the creation of the Peace Maze in 2000, one of the world's largest permanent hedge mazes, and the restoration of the Annesley Gardens as part of the 'Re-Rooting our past in the Future: Castlewellan Historic Demesne' project. The National Arboretum of Northern Ireland, located in the park, is home to a dendrological collection of exceptional merit, featuring trees from Asia, Australasia, and North and South America, including Japanese Maple and Giant sequoia planted in the 1850s.
