Our Lady Immaculate Church, Chelmsford

In 1840, the site for the church was bought. It was purchased from Charles King, the father of the first mission priest to the area. In 1845, the mission to Catholic population in Chelmsford was founded.[2]

In October 1847, the church was opened by the then Vicar Apostolic of the London District, Nicholas Wiseman. In 1850, he became Archbishop of Westminster and a cardinal. The church was originally dedicated to the Immaculate Conception. The architect was Joseph John Scoles. The main benefactors of the church were Charles King and William Petre, 12th Baron Petre. It was Lord Petre who chose Scoles to design the church. The church was built in the Gothic Revival style by the builders, Messrs Curtis of Stratford. The Lady altar in the church was originally in Thorndon Hall, home of Lord Petre. The east window in the church was made in Newcastle upon Tyne by Thomas Dunn and inspired by a design of Augustus Pugin.[2]

In 1973, the church was reordered and extended. A new altar was consecrated by the Bishop of Brentwood, Patrick Casey. In 1982, the church's dedication was changed the Immaculate Conception to Our Lady Immaculate. In 1985, the present organ was installed. It was brought from a United Reformed Church in Felsted. In 1988, the crucifix hanging over the altar in front of the nave was installed, it was designed by William Gordon.[2]
