What is the name of the main bell in 'St Paul's Cathedral' in London?

St Paul's Cathedral, London, is an Anglican cathedral, the seat of the Bishop of London and 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 1 listed building. Its dedication to Paul the Apostle dates back to the original church on this site, founded in AD 604. The present cathedral, dating from the late 17th century, was designed in the English Baroque style by Sir Christopher Wren. Its construction, completed in Wren's lifetime, was part of a major rebuilding programme in the City after the Great Fire of London.

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. At 365 feet (111 m) high, it was the tallest building in London from 1710 to 1967. The dome is among the highest in the world. St Paul's is the second-largest church building in area in the United Kingdom after Liverpool Cathedral.

The southwest tower contains four bells of which Great Paul, cast in 1881 by Taylor's bell foundry of Loughborough, Leicestershire, at 16½ tons was the largest bell in the British Isles until the casting of the Olympic Bell for the 2012 London Olympics. This bell has traditionally sounded at 1 o'clock each day. Great Paul has not been rung for several years because of a broken chiming mechanism.
