Southwick and North Bradley were home to one of the earliest and largest centres of the Baptist movement in the county. They were represented at Western Baptist Assembly Meeting of 1655 and at that time it was said that the members were numerous and influential. During the time of persecution, from 1660 to 1689 they met in Witch Pit Wood on the Cutteridge estate. This was owned by William Trenchard, died 1710, who was a Justice of the Peace and a Member of Parliament, sympathetic to the Baptist cause.Congregations of 1,000 and more met in a dell under the protection of Trenchard. In 1669 meetings were also being held in a field, attracting between 200 and 300 people, while in that year Major William King built a meeting house called Pig Hill Barn. This was on the road between Bradley and Southwick, near to Scotland, and could accommodate between 800 and 1,000 people. It was near Pig Hill Farm House, owned by Anthony Bissie, who came from an influential and ancient local family. He was a Baptist himself and was able to afford protection to the meeting. It was used until 1688, and probably to 1709, being only demolished in the 19th century.
