Holy Trinity Church was built in the centre of the village in 1844, to designs of T.H. Wyatt in Romanesque style, partly at the cost of the Church Building Commissioners, and partly at that of Thomas Phipps of Chalcot. A parish called Dilton's Marsh was created for the new church in 1845. The building is Grade II* listed. The small church of All Saints (a tin tabernacle) at Brokerswood, to the north of Dilton Marsh, was transferred from North Bradley parish in 1973. Today both churches are part of the White Horse Team Ministry, centred on Westbury.
