Holy Trinity Church, Westbury on Trym

Holy Trinity Church (grid reference ST5733177405) is a Church of England parish church in Westbury-on-Trym, Bristol, England.

The first church on the site was established in the 8th century. In the 10th century a Benedictine priory was founded. Construction of the present building began in the early 13th century and it has been rebuilt several times since. It has been designated by Historic England as a Grade I listed building.

From the late 12th century to the middle of the 16th century it was the collegiate church for Westbury College; of the latter, little more than the college gatehouse remains. The church contains the tomb of John Carpenter, Bishop of Worcester, who had planned to make it a joint cathedral for the Worcester diocese.
