14. St Paul's Cathedral, London, is a Church of England cathedral and seat of the Bishop of London. Its dedication to Paul the Apostle dates back to the original church on this site, founded in AD 604. St Paul's sits at the top of Ludgate Hill, the highest point in the City of London, and is the mother church of the Diocese of London. The present church dating from the late 17th century was built to an English Baroque design of Sir Christopher Wren, as part of a major rebuilding program which took place in the city after the Great Fire of London, and was completed within his lifetime. The cathedral is one of the most famous and most recognisable sights of London, with its dome, framed by the spires of Wren's City churches, dominating the skyline for 300 years. At 365 feet (111 m) high, it was the tallest building in London from 1710 to 1962, and its dome is also among the highest in the world. In terms of area, St Paul's is the second largest church building in the United Kingdom after Liverpool Cathedral. St Paul's Cathedral occupies a significant place in the national identity of the English population. It is the central subject of much promotional material, as well as postcard images of the dome standing tall, surrounded by the smoke and fire of the Blitz. Important services held at St Paul's include the funerals of Lord Nelson, the Duke of Wellington and Sir Winston Churchill; Jubilee celebrations for Queen Victoria; peace services marking the end of the First and Second World Wars; the marriage of Charles, Prince of Wales, and Lady Diana Spencer, the launch of the Festival of Britain and the thanksgiving services for both the Golden Jubilee and 80th Birthday of Queen Elizabeth II. St Paul's Cathedral is a busy working church, with hourly prayer and daily services. Top

It uses a mixture of live actors, special effects and rides. Opening in 1974, it was initially designed as more a museum of "horrible history", but the Dungeon has evolved to become an actor-led, interactive experience. The Dungeon is operated by Merlin Entertainments.
