After the accession of Elizabeth I in 1558, Catholics were forced out of the ancient parish churches of England. By Act of Parliament, Catholic worship ceased on 24 June 1559. They were forbidden from building their own churches and their only discreet refuge for Masses tended to be the chapels of the nobility and gentry. This position pertained, as regarded the law, until the passing of the Catholic Relief Act of 1791, although the chapels of the Catholic embassies in London were allowed to have Mass celebrated under the Treaty of Utrecht of 1714.
