Parish of St Paul, Onslow Square, Kensington , Church of England

Onslow Square was built between 1845 and 1865 on estate left by a wealthy seventeenth-century alderman Henry Smith. The architect of the church was James Edmeston. The exterior of the church is faced with Kentish rag and is basically Perpendicular in style with a distinctive slender spire. Saint Paul's was consecrated at Christmas 1860. One vicar, Hanmer Webb Peploe, whose incumbency was 1876-1909, made the church a noted centre of Evangelism. Memorial tablets include one to Sir Charles James Freake, who contributed most of the funds of the church and was the builder and developer responsible for the construction of the estate upon which the church stood.

In 1977 St Paul's united with Holy Trinity Brompton and the last service was on 1st May that year.
