Parish of St Mary the Boltons, West Brompton , Church of England

Saint Mary's Church (commonly known as Saint Mary the Boltons) was built in 1850 and consecrated in October of that year. A parish was assigned to the church in December 1850 out of the parish of Holy Trinity, Brompton Road, Kensington.

In 1854 a National School associated with Saint Mary's was established at Chelsea Grove, moving to Filston Road in 1878. The school was mixed until 1871 when it became a girls' and infants' school. At the outbreak of the Second World War Saint Mary's National School was scheduled for closure. It never reopened after its pupils were evacuated to the countryside.

By an Order in Council of December 1972 Saint Mary's absorbed the neighbouring parish of Saint Peter, Cranley Gardens, which had been created out of Saint Mary's in 1867. The united parishes became known as Saint Mary with Saint Peter, West Brompton. Saint Mary's remained the parish church. Records of Saint Peter's prior to the amalgamation are listed as P84/PET1.
