Perched on a granite outcrop above the shimmering waters of Castlewellan Lake, Castlewellan Castle is a striking example of Scottish baronial architecture. Constructed for the 4th Earl Annesley between 1856 and 1858, the castle was designed by the renowned Scottish architect William Burn and built from locally quarried granite by the Parker partnership of Liverpool. Today the building functions as a Christian conference centre, but its imposing towers, turrets and stone mullioned windows can be admired from the park’s main promenade.

The castle forms the visual focal point of Castlewellan Forest Park, a 460‑hectare woodland and lake complex that opened to the public in 1967. Its location on the edge of the historic walled garden offers sweeping views of the lake, the surrounding Mourne Mountains and the meticulously restored arboretum.

History

The Annesley family, who owned the extensive estate from the mid‑18th century, commissioned the castle after the death of the 4th Earl in 1874. The 5th Earl, Hugh Annesley, expanded the surrounding arboretum, planting over 1,800 species of trees and shrubs, many of which survive today as champion specimens. The 6th Earl, Francis, inherited the estate in 1908 but was killed in the First World War; the property subsequently passed to Lady Mabel Annesley, who later sold it to the government.

After a decade of vacancy, the castle was repurposed in 1974 as a Christian conference centre, a role it retains. Its historic interiors have featured in film productions such as Woman in White (2018) and Mickeybo and Me (2004), adding a cinematic footnote to its storied past.

What to See & Do

While the interior is not open to the general public, the exterior and surrounding grounds provide ample photographic opportunities. Visitors can:

  • Admire the façade: The granite walls, crow‑stepped gables and conical turret roofs exemplify the baronial style.
  • Enjoy lake views: A short walk from the castle leads to the Lakeside Walk (2.4 mi / 3.9 km), a flat, circular route that circles the lake and offers panoramic vistas of the castle, Slievenaslat and the Mourne range.
  • Explore the arboretum: The Castlewellan Arboretum, established in 1740, lies immediately behind the castle. It houses over 700 taxa, including giant sequoias planted in the 1850s and the award‑winning ‘Castlewellan Gold’ Leylandii.
  • Visit the Peace Maze: Just a few minutes’ walk from the castle, the 6,000‑yew‑tree maze, created in 2000, provides a contemplative contrast to the stone stronghold.
