Our Lady of Hal is the Catholic parish church for the Camden Town area of London. Designed by the architect (1884-1968), it was commissioned by The Missionary Fathers of Scheut, also known as the Congregation of the Immaculate Heart of Mary (CICM), and was originally intended to be a church for the many Belgian refugees who were living in London. It replaced smaller chapel on the opposite side of the road from the present church, which had begun to minister to the needs of the local Catholic community in 1922. The foundation stone was laid on 17th July 1932, and the church was blessed and opened on 18th March 1933. Wilfred Clarence Mangan designed many Catholic churches, and another was St Barnabus' Church, Molesley in Surrey, which was built in 1931 and also replaced a smaller church in the same area.
