Parish of Holy Trinity, Clapham , Church of England

Holy Trinity was the Ancient parish of Clapham; and an earlier church of that name stood on the site now occupied by Saint Paul's, Rectory Grove. With the increase in population in this area the original church was not considered large enough. The new Holy Trinity was built in 1774-1779 on the common. The architect was Kenton Couse who was also responsible for 10 Downing Street. Consecration took place in June 1776. The burial ground around the old church, later known as Saint Paul's Churchyard, remained in use until 1855 as no burials took place in the churchyard around the present Holy Trinity. In 1812 the portico was added by Francis Hurlbatt. The church was considerably altered in 1875 to A. Blomfield's designs.

Holy Trinity was well known as the church of The Clapham Sect which included Zachary Macaulay, Granville Sharp, William Wilberforce and Henry Thornton. The Sect are commemorated by a plaque.

The church suffered damage during the Second World War when the Lady Chapel was burnt out by incendiary bombs. Restoration and repairs were carried out under the direction of Thomas Ford. Friday 6 June 1952 saw the Rededication of the church following completion of the works.
