Newcastle has three cathedrals, the Anglican St. Nicholas, with its elegant lantern tower of 1474, the Roman Catholic St. Mary's designed by Augustus Welby Pugin and the Coptic Cathedral located in Fenham. All three cathedrals began their lives as parish churches. St Mary's became a cathedral in 1850 and St Nicholas' in 1882. Another prominent church in the city centre is the Church of St Thomas the Martyr which is the only parish church in the Church of England without a parish and which is not a peculiar.
