Berwick-upon-Tweed’s Holy Trinity parish church is unique because it is the only such church to be built during the Commonwealth of Oliver Cromwell. Sometimes called the Cromwellian Church, its foundation stone was laid in 1650 with completion in 1652. Set within the Elizabethan walls, the church has no tower, spire or bell, and was built with stones from the town’s 13th century castle. Inside, visitors can see the original communion table, unique reredos designed by Sir Edwin Lutyens, a stunning rose window and other stained glass windows containing 17th century Flemish roundels.
