Church of Our Lady of the Assumption & St Gregory
Warwick Street
Dedicated to the Life of the Ordinariate of Our Lady of Walsingham.
The chapel which existed behind the house of the Portuguese Ambassadors after 1724, was evidently situated between the two houses on Golden Square and the stables which fronted on Warwick Street. Thus the chapel itself was much smaller than the present church and probably invisible from either the Golden Square side or the Warwick Street side. English Catholics could use Embassy Chapels but did not have permission to have chapels or churches of their own until the passing of the Second Catholic Relief Act of 1791.
