Overview & History
Royal Hillsborough sits just 15 km south-west of Belfast in County Down. Known locally by its Irish name Cromghlinn (“crooked glen”), the village earned its royal prefix in October 2021, becoming the first settlement in Northern Ireland to carry the title. The honour recognises centuries of connection to the Crown, dating back to 1661 when the settlement was renamed Hillsborough after Sir Moses Hill and his son Sir Arthur, who built a fort here in 1650.
The Hill family later became Earls and then Marquesses of Downshire, shaping the area’s Georgian streets and grand estates. Their most famous legacy is Hillsborough Castle, constructed in 1770 and serving as Government House from 1924. The castle’s State Rooms have hosted pivotal moments in modern Irish history, including the 1985 Anglo-Irish Agreement and the early talks that paved the way for the Good Friday Agreement. American founding father Benjamin Franklin even visited in 1771, escorted through the grounds by Wills Hill, underscoring the estate’s long diplomatic pedigree.
Hillsborough Castle & Gardens
The castle sits at the heart of 100 acres of meticulously landscaped grounds. Interior tours focus on the State Rooms, including the Throne Room, State Drawing Room and Red Room, where period furniture and portraits illustrate centuries of state visits and political negotiations. Exterior photography is welcome, but cameras are not permitted inside to protect the historic interiors.
Beyond the mansion, the gardens unfold into a series of distinct spaces. The Walled Garden produces seasonal flowers and vegetables, much of which supplies the on-site café. The Granville Garden, named after former Prime Minister Granville Leveson-Gower, features tranquil water features and carefully curated plantings. A short walk leads to the Lady Alice Temple, a stone structure framed by reflective ponds and mature trees. For younger visitors, the Imaginary Menagerie trail uses storytelling stations to bring woodland creatures to life, making it easy to keep children engaged while exploring.
Hillsborough Forest & Trails
A short walk from the castle gates, Hillsborough Forest covers nearly 200 acres of mixed woodland and lake. It’s a popular spot for birdwatchers, dog walkers and families looking for free, unstructured outdoor time. Three colour-coded trails cater to different paces and interests:
- Lake Trail (1.8 km circular): Flat terrain with lakeside benches and optional side routes. Ideal for a relaxed stroll.
- Fox Fort Trail (3.4 km circular): Passes the historic Fox Fort Rath and a woodland playground. Includes a modest hill segment, which can be skipped for a completely level loop.
- Digital Sculpture Trail (1.9 km circular): Features ten augmented-reality sculptures accessible via a free app, blending nature with interactive technology.
All pathways are wide and relatively flat. Free parking for 137 cars (including six disabled bays) is available at the main entrance. The forest play area operates year-round, with extended summer hours (Mon 10:30–21:00, Tue–Sun 09:00–21:00) and winter hours (Mon 10:00–17:00, Tue–Sun 09:00–17:00).
Village Life & Dining
The village centre retains a strong local character. The Square is home to The Plough Inn, a traditional pub offering a two-course lunch (£12) and early evening dinner (£13.95). Live acoustic music runs through weekends, and Thursday quiz night draws regulars from the surrounding area. The pub provides high chairs, baby-changing facilities, gluten-free options on request, and a dog-friendly outdoor patio.
Walking the village streets reveals the Monument to the 3rd Marquess of Downshire, a tall column modelled on Nelson’s Column that dominates the southern skyline. St Malachy’s Parish Church (1760–1774) stands as a fine example of Gothic Revival architecture, housing two historic organs and a peal of ten bells. In September, the whole village turns its attention to the International Oyster Festival, a multi-day event featuring fresh seafood, garden fêtes, boat races and parachuting displays.
Practical Information
Getting there: Royal Hillsborough is easily reached from the A1 dual carriageway. Brown tourist signs direct visitors to the castle car park. Translink bus routes 238 and 38 connect Belfast and Newry with stops in the village centre. A well-signposted footpath links the high street to the castle grounds.

Accessibility & dogs: Guide dogs are welcome throughout the castle and forest. Disabled toilets are available at both locations.

Nearby Attractions
A short drive takes you to other County Down landmarks. Head north-west to Bagenal’s Castle, a 16th-century tower house overlooking the River Bann, or follow the coast to Bangor, where a medieval abbey and bustling marina sit just minutes from the shoreline.
