Facilities Nestled snugly in the rolling countryside of the South West, Priston Mill's prestigious 'Watermill' was constructed in 1720 and simply oozes character. With the Mill's well-preserved traditional features and breathtaking views, it makes the perfect setting for your wedding party, an ideal backdrop for photos and relaxed celebrations. The Watermill can accommodate up to 90 seated diners and 130 evening party guests, offering superior cuisine and staff that are committed to catering to your every need. Priston Mill's alternative venue, the 'Tythe Barn', was also built in 1720, and is best suited for weddings with between 80-160 guests, and up to 200 for the evening party. The exposed oak beams of the pitched roof and unique stone features differentiate the Tythe Barn from other wedding venues, making it the number one choice for many marrying couples around the Bath area, or even considerably further afield.
