The Cathedral Church of St Thomas of Canterbury, commonly known as Portsmouth Cathedral, is an Anglican cathedral church in the centre of Old Portsmouth in Portsmouth, England. It is the cathedral of the Diocese of Portsmouth and the seat of the bishop of Portsmouth. The Anglican cathedral is one of the two cathedral churches in the city, the other being the Roman Catholic Cathedral of St John the Evangelist, Portsmouth, about one mile to the north. History Around the year 1180, Jean de Gisors, a wealthy Norman merchant and Lord of the Manor of Titchfield, gave land in his new town of Portsmouth to the Augustinian canons of Southwick Priory so that they could build a chapel "to the Glorious Honour of the Martyr Thomas of Canterbury, one time Archbishop, on (my) land which is called Sudewede, the island of Portsea". It was given so that they could build a chapel dedicated to the honour of St Thomas of Canterbury, who was assassinated and martyred ten years earlier. This chapel was to become, in turn, a parish church in the 14th century and then a cathedral in the 20th century. The medieval building, dedicated in 1188, was cruciform in shape, with a central tower, which was used as a lookout point and lighthouse, over the crossing. Of the original building, only the chancel and the transepts remain. The church survived a French raid in 1337 which had laid waste most of Portsmouth during the Hundred Years War. However, in 1449, Adam Moleyns, Bishop of Chichester, was murdered by local sailors. The town's inhabitants were excommunicated and the church was closed. In 1591, Elizabeth I worshipped in St Thomas's Church. During the English Civil War, when the Parliamentary forces attacked the town in 1642, the Royalist garrison used the church tower to observe the movement of enemy forces. Parliamentary gunners positioned in Gosport fired on the tower and inflicted damage to the church. This resulted in the ruin of the medieval tower and nave. With the restoration of the monarchy in 1660 came the authorisation by Charles II for a collection in churches across the country to raise the £9,000 required to rebuild the tower and nave, which took place from 1683 to 1693. The nave was built in the classical style. Galleries were added in 1708 to cater for growing congregations, and were extended in 1750. The wooden cupola with
