St Paul's Cathedral is an Anglican cathedral dedicated to Paul the Apostle. It sits at the top of Ludgate Hill, the highest point in the City of London, and is the seat of the Bishop of London. The present building dates from the 17th century and was designed by Sir Christopher Wren. It is generally reckoned to be London's fifth St Paul's Cathedral, all having been built on the same site since AD 604. The cathedral is one of London's most famous and most recognisable sights. At 365 feet (111m) 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.
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 launch of the Festival of Britain and the thanksgiving services for both the Golden Jubilee and 80th Birthday of Queen Elizabeth II. The British Royal Family holds most of its important marriages, christenings and funerals at Westminster Abbey, but St Paul's was used for the marriage of Charles, Prince of Wales, and Lady Diana Spencer. St Paul's Cathedral is still a busy working church, with hourly prayer and daily services.
