Holy Trinity Brompton with St Paul's, Onslow Square and St Augustine's, South Kensington, often referred to simply as HTB, is an Anglican church in London, England. The church consists of six sites: HTB Brompton Road, HTB Onslow Square (formerly St Paul's, Onslow Square), HTB Queen's Gate (formerly St Augustine's, South Kensington), HTB Courtfield Gardens (formerly St Jude's Church, Kensington – officially in the parish of St Mary of the Bolton's but part of HTB), as well as being the home of the St Paul's Theological Centre and the Alpha Course, HTB St. Francis Dalgarno Way and St Luke's Earls Court St Luke's Church Redcliffe Gardens. It is where the Alpha Course was first developed and is one of the most influential churches in the Church of England. The church buildings accommodate Alpha, other courses, conferences and meetings during the week and ten services each Sunday. With total Sunday service attendance at around 4,500 people and the Alpha course attracting several hundred guests during the week, HTB oversees a diverse range of activities. HTB's vision statement is to "play our part in the evangelization of the nations, the revitalization of the church and the transformation of society." HTB's aim is for an Alpha Course to be accessible to anyone who would like to attend the course. In this way, HTB seeks to spread the teachings of Christianity. Nicky Gumbel, the developer of the Alpha course, took over as vicar of HTB from Sandy Millar in July 2005, followed by Archie Coates in September 2022. The associate vicar is Katherine Chow, who took over from Nicky Lee and Martyn Layzell in 2020. History Holy Trinity Prior to the construction of Holy Trinity Brompton, the present site was a part of the large parish of Kensington which was served only by the nearby St Mary Abbots church. In the early 1820s the area was in the midst of a substantial population increase, so a decision was taken to purchase land and construct a new church. The church was a Commissioners' church, receiving a grant from the Church Building Commission towards its cost. The full cost of the church was £10,407 (), towards which the Commission paid £7,407. The architect was Thomas Leverton Donaldson. Holy Trinity is a Grade II listed building. After three years of construction, the church was consecrated on 6 June 1829 by the Bishop of London.
