Many Anglican churches were damaged or destroyed during World War II, and most were not replaced. The "beautiful and sensitive" restoration of the Church of the Holy Spirit in the 1950s brought the 150-year era of intensive churchbuilding in the city to an end: as congregations and financial resources have reduced, more churches have closed or been replaced by smaller buildings (as at St Mark's, North End) or adapted into multi-purpose community facilities (as at St Cuthbert's, Copnor). In the 18th century, Portsea Island's few Roman Catholics travelled to Gosport to attend Mass, crossing Portsmouth Harbour in a rowing boat, or to Havant. Both of these missions were in private chapels in houses belonging to Catholic families, as churches for public worship could not be built until the passing of the Roman Catholic Relief Act 1791. In that year or 1792 a temporary chapel opened in central Portsmouth. Four years later a permanent church was built behind houses on Prince George Street. As the population grew it was enlarged in the mid-19th century, galleries were added and a schoolroom was built. It was superseded by the present cathedral, but survived in commercial use until 1965. The present Cathedral of St John the Evangelist was founded in 1880 and was raised to cathedral status two years later when the Diocese of Portsmouth was created. Two years later a mission dedicated to Our Lady and St Swithun was founded in Southsea, and a tin tabernacle was erected to serve as a chapel of ease. The present St Swithun's Church replaced it in 1901. In 1893 a second mission was established in the North End district, and Corpus Christi became Portsmouth's third Catholic church. St Joseph's Church was built in 1914 to serve the Copnor district, where Mass had been celebrated since 1908, and a church opened in a converted garage in 1937 in Eastney. The permanent replacement, a prefabricated building dedicated to Our Lady of Lourdes, opened in 1956. On the mainland, churches were built in Cosham (1928) and on the Paulsgrove estate (1970). Other churches in the city with a Catholic tradition are St Agatha's Church at Landport (originally Anglican, but now affiliated with the Roman Catholic Church through the Personal Ordinariate of Our Lady of Walsingham) and the Church of Our Lady Help of Christians in Kingston, part of the traditionalist Society of Saint Pius X. Methodism "has had an important influence on the religious and social life of Portsmouth" since the 18th century.
