St Paul's Cathedral is an Anglican cathedral in London. As the seat of the Bishop of London, the cathedral serves as the mother church of the Diocese of London. It sits on Ludgate Hill at the highest point of the City of London and is a Grade I listed building. 

Its dedication to Paul the Apostle dates back to the original church on this site, founded in AD 604. The present structure, dating from the late 17th century, was designed in the English Baroque style by Sir Christopher Wren. 

The cathedral is one of the most famous and most recognisable sights of London. Its dome, framed by the spires of Wren's City churches, has dominated the skyline for over 300 years.
