Craig y Nos Castle is a wedding and event venue in the Brecon Beacons, at Craig y Nos near Swansea in South Wales. Couples can book the whole castle for a day: a ceremony in the Adelina Patti Theatre, a meal in the conservatory, an evening party in a function suite, and bedrooms for guests on site. The castle also runs public events such as murder mystery dinners and ghost tours.
Seminars and company events
The pages we read present the castle mainly as a wedding venue and a hotel, with an events programme open to the public. They do not describe a meetings offer, so ask the team whether a company dinner, a team weekend or a group stay can be arranged. Group accommodation is listed, including a self-contained Nurses Block that can be booked room by room or as a whole, with a lounge and a small communal kitchen. The castle also offers dry hire for weddings, which suggests the building can be hired on its own terms.
Weddings and receptions
Weddings are the main business. The castle is exclusively yours for a wedding: you and your guests use the whole building, and no other wedding takes place at the same time. The ceremony can be held in the Adelina Patti Theatre, the castle's Grade I listed historic opera house. The drinks reception takes place in the Nicolini Lounge, the lounge and bar at the entrance. The wedding breakfast is served in the conservatory, which looks over the country park. In the evening, guests move to a separate function suite connected to the Nicolini Lounge. A bridal get-ready room with a private terrace is available for the morning. The packages include welcome drinks, canapes, a three course wedding breakfast, an evening buffet option, chair covers and table linen. The castle also lists non-exclusive weddings in the opera house for small groups of 10 to 20 guests, a winter package for 50 people, a weekend package for large groups, and a dry hire option.
