The Church of Our Lady of the Assumption and St Gregory is a Catholic church on Warwick Street, Westminster. It is the oldest Catholic church in England (excluding those used as Anglican churches and then returned to Catholic usage). It was formerly known as the Royal Bavarian Chapel, because like several Catholic churches in London it originated as a chapel within a foreign embassy. It was built between 1789 and 1790 to the designs of Joseph Bonomi the Elder.^[1] The only surviving eighteenth-century Catholic chapel in London,^[1] it is a Grade II* listed building.^[2] The parish is now operated by the Personal Ordinariate of Our Lady of Walsingham, the British personal ordinariate for the Anglican Use within the Catholic Church, and acts as its central church.^[3]
