There has been a Church on this site for at least 500 years.The original dedication was to St. Giles, but between 1691 and 1720 the old Church was demolished and a new one, dedicated to the Holy Trinity, erected in its place. In 1854 the Bishop of Gloucester and Bristol, Bishop Monk, whose official residence was what is now Colston’s School, offered to rebuild the Church at his own cost, desiring “my fellow parishioners to understand that my motives in this work are to remove the source of dispute and contention for pews, caused by the inadequate size of the Church, and to provide sittings for the poor as well as other classes of Parishioners”. The Chancel was rebuilt at the cost of the lay rector, Greville Smyth, and the new Church was dedicated on 15 April 1857. The Choir Vestry was added in 1892.
This dates from 1857 and is of alabaster set on marble pillars. The oak cover is a memorial to two members of the Hall family who fell in the First World War.
This seems to have been made for some other church where the steps would have wound round a pillar. The Caenstone body rests on serpentine shafts with foliated capitals. and three of the panels contain carved representations of preaching – Christ in the centre, and St Peter and St Paul on the left and right respectively.
