Heritage Open Day: This church is a building of exceptional historic importance, a very rare example of a Commonwealth period church. Join Charles Bothwick in a guided walk exploring art and symbolism in the message and meaning of some of its stained glass windows When George Fenwick was Governor of Berwick in the 17th century, funds were raised to build the church using stone and timber from the disused Castle. It was completed in 1652. It was designed and built as a Puritan place of worship consisting of a regular nave with 2 side aisles and no chancel. It has no tower or steeple, reputedly at the express orders of Oliver Cromwell. This is the most northerly Anglican Church in England and the only example of a Commonwealth Church still actively used for worship today.
