Holy Trinity Church at Wetheral is an early 16th Century church, with an octagonal tower, in a commanding position overlooking the River Eden. It is said that the Church was formerly dedicated to St Constantine, the only church in England with that dedication.
The doorway is probably of 1790, when the tower was built, and the upper part belongs to the restoration of 1882. The chancel was largely rebuilt by Withers in 1872, but on the South side are two original inscriptions for Prior William Thornton of Wetheral Priory and his successor. In 1791 a mausoleum for the Howard Family was added, built in the Gothic style.
