Just behind the Municipal Chambers rise the twin white stone spires of St Paul's Cathedral, one of Dunedin's finest buildings and the seat of Anglican worship in the city. This impressive Gothic Revival edifice, entirely constructed from Oamaru stone was consecrated in 1919. Inside, the 65-metre-high stone-vaulted ceiling is the only one of its kind in New Zealand, and much of the stained glass in the impressive windows is original; the stark modern chancel and altar were added in 1971.
