Church of England St Denys's Church is the town's oldest, and is claimed to have had
minster status, as there was a church here in the 10th century. Rebuilding was carried out in the 14th century, and in 1889 the church was mostly rebuilt, with a longer nave. As the town's population grew in the 19th century, two more churches were built:
Christ Church in 1831 to serve the south of the town, and
St John's in 1865 in the southeast. All three churches are
listed, St Denys' and St John's churches are Grade II* and Christ Church is Grade II.
Town chapel The chapel of St Lawrence, on the High Street near the market place, has been a
chapel-of-ease to St Denys since at least 1290. Its tower is from the late 13th or early 14th century, but the rest was rebuilt in 1855–7. The people of the town bought the chapel in 1574, giving it the status of a
non-royal peculiar outside the jurisdiction of the Church of England. Since then has been administered by
feoffees (trustees) on behalf of the town, and they invite the vicar of St Denys' to hold services.
Others Methodists built a chapel on George Street, west of the town centre, in 1804; it was rebuilt in 1861. The congregation amalgamated with the
United Reformed Church in 1983 to form the United Church. A predecessor of the URC opened a chapel at Common Close in 1720, which by 1829 had a congregation of 900, leading to the chapel being rebuilt for a second time in 1839; notable ministers included
Daniel Fisher (1752 to 1771) and
Geoffrey Nuttall (1938 to 1943). Numbers fell in the 20th century, and after the 1983 amalgamation the chapel was demolished in 1987. Its interior was remodelled c.1850. St Giles' Garrison Church, Imber Road, was built in 1968. St George's Roman Catholic Church, Boreham Road, in the
Diocese of Clifton, was built in 1922 to designs of Bristol architect
Sir Frank William Wills.
College and convent James Erasmus Philipps, vicar of St Denys from 1859 to 1897, raised funds in 1860 to found a college for young men in a house on Church Street. Philipps also led the foundation of an order of
nuns, the
Community of St Denys, in 1879. The nuns ran St Monica's School for Girls, which merged with Lord Weymouth's Grammar School in 1973 to form Warminster School. Since the retirement of the last nun in the early 21st century, the order operates as a grant-making charity. == Notable buildings and structures ==
