 The Cathedral had been built quickly and economically, and this led to problems with the fabric of the building, including leaks. A programme of repairs was carried out during the 1990s. The building had been faced with mosaic tiles, but these were impossible to repair and were replaced with glass-reinforced plastic, which gave it a thicker appearance. The aluminium in the lantern was replaced by stainless steel, and the slate paving of the platform was replaced with concrete flags.
