Bury St Edmunds Cathedral was created when the Diocese of St Edmundsbury and Ipswich was formed in 1914. The cathedral was extended with an eastern end in the 1960s, commemorated by Benjamin Britten's Fanfare for St Edmundsbury, and a new Gothic revival cathedral tower was built as part of a millennium project running from 2000 to 2005. The opening for the tower took place in July 2005, and included a brass band concert and fireworks. Parts of the cathedral remain uncompleted, including the cloisters. Many areas remain inaccessible to the public due to building work. The tower makes St Edmundsbury the only recently completed Anglican cathedral in the UK, and only a handful of Gothic revival cathedrals are being built worldwide. The tower was constructed using original fabrication techniques by six masons who placed the machine pre-cut stone individually as they arrived.
