St Mary's Collegiate and Parish Church is an Anglican Church in the centre of Swansea, Wales, UK. It is considered the Civic Church of Swansea.
There was a church on the site of St Mary's since circa 1328, erected by Henry de Gower, Bishop of Saint David's. One Sunday morning, in 1739, the roof of the nave collapsed into the church. Fortunately this was before the waiting congregation entered the building. The whole structure was re-built apart from the tower. 1822 saw the church being lit by gas for the first time with thirty six lamps. The church underwent complete renovation between 1879 and 1882 by Vicar Dr Morgan. In 1896, the church was flattened and rebuilt again under the designs of Arthur Blomfield by Dean Allan Smith, though some parts of the old church survived the re-development. In Feb 1941 the Church was extensively damaged by Bombing during the Blitz It was not rebuilt until the 1950s
From the 1890s the Swansea Devil stood on a set of buildings facing the west side of the church, constructed by a disgruntled rival of Blomfield's, angry at the commissioning of Blomfield's designs over his own.
The tower contains eight bells, which were cast in 1959 by John Taylor & Co, Loughborough with the heaviest weighing 20cwt - 2qr - 12lb (1049.2 kg) in "E". Details of the bells:-
