You may be looking for Old St. Paul's Cathedral, a destroyed cathedral in the City of London.
Or for Old Saint Paul's, Edinburgh, of the Scottish Episcopal Church.
Old St. Paul's is an historic site, a Wellington landmark and a popular wedding- and event-venue in the heart of Wellington, the capital city of New Zealand. The building functioned as the cathedral of the Diocese of Wellington of the Anglican Church in Aotearoa, New Zealand and Polynesia between 1866 and 1964. It exemplifies 19th-century Gothic Revival architecture adapted to colonial conditions and materials, and stands at 34 Mulgrave Street, Thorndon, close to the New Zealand Parliament.
