Outside, the Church looks like one of the many such establishments in the area. But inside, it's a different view altogether. It is very beautiful, a fine piece of architecture which, as described in the Old St Paul's website, is of the Gothic Revival:
Old St Paul's is a fine example of 19th century Gothic Revival architecture adapted to colonial conditions and materials. Designed by the Reverend Frederick Thatcher, then vicar of St Paul's parish Thorndon, the first Anglican cathedral of Wellington is considered his best work. Constructed entirely from native timbers, the glowing interior is enhanced by stunning stained glass windows. Memorial items and displays tell the early history of Wellington.While it is no longer a Parish Church, it is still consecrated. And although it is Anglican in origin, the Church has become a non-denominational venue for weddings, baptisms, and other services.
