Old St Paul's is a historic site, a city landmark, and a wedding and event venue in the heart of Wellington, the capital city of New Zealand. The building served a dual role as the parish church of Thorndon and the pro-cathedral of the Diocese of Wellington of the Anglican Church between 1866 and 1964. It exemplifies 19th-century Gothic Revival architecture adapted to colonial conditions and materials, and stands at 34 Mulgrave Street, Pipitea, close to Parliament Buildings.
