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 while the congregation was waiting to enter 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 February 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.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
