We have 4 rooms which are ideal for your ceremony, or for the celebration, or both, a restaurant where we serve our delicious home grown bio-dynamic vegetarian meals, various communal areas and break-out rooms for those seeking some peace and quiet. And we can accommodate up to 30 guests within our 20+ bedrooms, most of which have stunning views. Your ceremony can either be held within Trigonos, or (weather permitting) outside! For weddings with a guest list of 60+ we would recommend a marquee be set up on one of our meadows, which we will supply with sufficient notice. For your celebration we do not have an alcohol licence, but we are able to recommend a local company who are able to install and stock a mobile bar for the day. If you wish to use one of our 4 event rooms for the day, we will tastefully decorate the room, or alternatively you are welcome to decorate the room in your own style, and with notice we can ensure that the room is available for you on the day before the celebrations. We are also able to provide you with a Wedding Planner who works alongside us, and can arrange for all your needs – music, cars, and any of the other requirements that can cause stress on the day! In addition, to remember the day, we will plant a tree within our grounds with a plaque with the Bride and Groom’s names and the special date… ## Additional Features - Marquee Facilities - Wedding Planner - Civil Licence ## Facilities - **Accessibility:** All public areas such as meeting rooms and dining room are on the ground floor and suitable for wheelchair access.
