in 1925. Religion Portsmouth has two cathedrals: the Anglican Cathedral of St Thomas in Old Portsmouth and the Roman Catholic Cathedral of St John the Evangelist. The city is one of 34 British settlements with a Roman Catholic cathedral. Portsmouth's first chapel, dedicated to Thomas Becket, was built by Jean deGisors in the second half of the 12th century. It was rebuilt and developed into a parish church and an Anglican cathedral. Damaged during the 1642 Siege of Portsmouth, its tower and nave were rebuilt after the Restoration. Significant changes were made when the Diocese of Portsmouth was founded in 1927. It became a cathedral in 1932 and was enlarged, although construction was halted during the Second World War. The cathedral was re-consecrated before Queen Elizabeth The Queen Mother in 1991. The Royal Garrison Church was founded in 1212 by Peter des Roches, Bishop of Winchester. After centuries of decay, it became an ammunition store in 1540. The 1662 marriage of CharlesII and Catherine of Braganza was celebrated in the church, and large receptions were held there after the defeat of Napoleon at the 1814 Battle of Leipzig. In 1941, a firebomb fell on its roof and destroyed the nave. Although the church's chancel was saved by servicemen shortly after the raid, replacing the roof was deemed impossible due to the large amounts of salt solution absorbed by the stonework. The Cathedral of St John the Evangelist was built in 1882 to accommodate Portsmouth's increasing Roman Catholic population, and replaced a chapel built in 1796 to the west. Before 1791, Roman Catholic chapels in towns with borough status were prohibited. The chapel opened after the Roman Catholic Relief Act 1791 was passed, and was replaced by the cathedral. It was constructed in phases; the nave was completed in 1882; the crossing in 1886, and the chancel by 1893. During the blitz, the cathedral was badly damaged when Luftwaffe bombing destroyed Bishop's House next door; it was restored in 1970, 1982, and 2001. The Roman Catholic Diocese of Portsmouth was founded in 1882 by Pope Leo XIII. Smaller places of worship in the city include StJude's Church in Southsea, StMary's Church in Portsea, StAnn's Chapel in the naval base and the Portsmouth and Southsea Synagogue, one of Britain's oldest. Other places of worship include the Immanuel Baptist Church, Southsea; Trinity Methodist Church, Highland Road; Buckland United Reformed Church; The Oasis Centre
