Westminster Cathedral
The site on which the cathedral stands in the City of Westminster was purchased by the Diocese of Westminster in 1885, and construction was completed in 1903. Westminster Cathedral is the largest Catholic church building in England and Wales and the seat of the Archbishop of Westminster.
Westminster Chapel
The congregation was formed in 1840 and its original chapel building was completed in Buckingham Gate in 1841. The congregation outgrew that building, so construction of a new chapel was begun in 1864. This building is the present chapel. It opened on 6 July 1865 and has capacity to seat about 1,500 people.
