Peterborough Cathedral, properly the Cathedral Church of St Peter, St Paul and St Andrew – also known as Saint Peter's Cathedral in the United Kingdom – is the seat of the Anglican Bishop of Peterborough, dedicated to Saint Peter, Saint Paul, and Saint Andrew, whose statues look down from the three high gables of the famous West Front. Although it was founded in the Anglo-Saxon period, its architecture is mainly Norman, following a rebuilding in the 12th century. With Durham and Ely cathedrals, it is one of the most important 12th-century buildings in England to have remained largely intact, despite extensions and restoration.

The term Norman architecture is used to categorise styles of Romanesque architecture developed by the Normans in the various lands under their dominion or influence in the 11th and 12th centuries. In particular the term is traditionally used for English Romanesque architecture. The Normans introduced large numbers of castles and fortifications including Norman keeps, and at the same time monasteries, abbeys, churches and cathedrals, in a style characterised by the usual Romanesque rounded arches and especially massive proportions compared to other regional variations of the style.
