Portsmouth Cathedral, officially known as the Cathedral Church of St Thomas of Canterbury, is an Anglican cathedral church in Portsmouth, England. It is the cathedral of the Diocese of Portsmouth and the seat of the bishop of Portsmouth. The cruciform building was constructed in the Romanesque style on land donated by Norman lord Jean de Gisors in the 1180s and dedicated to Saint Thomas Becket, who was martyred around ten years earlier. It was made a cathedral upon the establishment of the Diocese of Portsmouth, which was split from the Diocese of Winchester in 1927, after which it was extended in a "Neo-Byzantine" style by Charles Nicholson.
This picture shows the cathedral's chancel, which, along with the transepts, are the only remaining sections of the original medieval building. The baptismal font, made to a ninth-century Greek design, is placed in the centre.Photograph credit: David Iliff
