Hillsborough Castle and Gardens

Hillsborough Castle has been the residence of the Royal Family in Northern Ireland since the 1920s, although its origins stretch right back to the 18th century. Since the 1970s, the castle has served as a venue for various stages of the Peace Process in Northern Ireland, and has played host to monarchs, minsters, presidents and princesses.

Hillsborough Castle makes an inspiring venue for events of all sizes. Elegant, yet relaxed. Graceful and intimate – it’s a magical venue located just 20 minutes from Belfast. Whatever event you’re planning, you’ll enjoy professional service from an events team dedicated to your ideas and vision.

For large-scale events, conferences and award ceremonies, the gardens provide ample opportunity for marquees large enough for 350 people, set amongst pretty terraces and decorative lawns. For smaller functions, the castle’s State Rooms offer a regal opulence that is sure to impress. From intimate dinners in the State Dining Room, to conferences and presentation for up to 120 people in the grand Throne Room, each of the state rooms has its own unique character, but all are guaranteed to add a sense of occasion and ceremony to your event. Enjoy free Wi-Fi and disabled access throughout.
