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.
Old St Paul's Cathedral
According to the architectural historian John Harvey, the octagonal chapter house, built about 1332 by William Ramsey, was the earliest example of Perpendicular Gothic. This is confirmed by Alec Clifton-Taylor, who notes that the chapter house and St Stephen's chapel at Westminster Abbey predate the early Perpendicular work at Gloucester Cathedral by several years. The foundations of the chapter house were recently made visible in the redeveloped south churchyard of the new cathedral.
