walls only are brick. Dilton Marsh was a tithing of the ancient parish of Westbury, and the church at Dilton (now Old Dilton) was a chapelry of the parish church at Westbury. Dilton Marsh civil parish was created in 1894, bounded on the east by the Biss Brook and on the west by the county boundary; the southern extent of the new parish was reduced in 1934 when Chapmanslade civil parish was created. Dilton Marsh had two schools in the 19th century. A British School was built in 1866, enlarged in 1884 and 1895, and became a County school 1906. A National School was built next to the new church c. 1848, and became a County school in 1904, when it was known as the Church of England school. The schools took children of all ages until the 1930s, when those over 11 transferred to the secondary school at Westbury. In 1938, the sites were reorganised into an Infants' school at the former British School, and a Junior school at the church school. Notable buildings Chalcot House, a Grade II* listed country house, stands in Chalcot Park in the south of the parish.

Bremeridge Farmhouse, in farmland about north of the High Street, was thought to date from the 18th century until investigation in 2021 found within the substantial stone house a smaller timber-framed house from the second half of the 16th century. Religious sites St Mary's Church, Old Dilton is from the 14th century, with later work in the 15th and 17th; its interior is little changed since the 18th. It was always a chapelry of All Saints', Westbury. Regular services ceased in 1900 after the building of Holy Trinity at Dilton Marsh, and the church was declared redundant in 1973. A Grade I listed building, it is now in the care of the Churches Conservation Trust. 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
