St. Mary's is one of very few churches built in England during the reign of George I. It was constructed in 1723 to replace the Lady Chapel of Kingswood Abbey, where the people of Kingswood had worshipped since the Dissolution and which had fallen into disrepair. The adjacent Abbey Gatehouse is a national monument, administered by English Heritage.
St. Mary's is part of the United Benefice of Wickwar with Rangeworthy and Hillesley and Charfield with Kingswood. Our Parish Priest is the Rev'd Canon David Russell.
