If you plan to arrive in London or are already in it, no matter whether you are a Christian or a member of another faith, or do not believe you simply have to to visit St. Paul’s Cathedral, and marvel at the Anglican cathedral from 17th century. The current St Paul's Cathedral in London, the fourth to occupy the site, was designed by the Sir Christopher Wren and built between 1675 and 1710 after its predecessor was destroyed in the Great Fire of London. The 360ft high dome which dominates the city's skyline is the second largest in the world. The church itself is the largest Protestant church in England. From inside too, the dome is stunning and it is well worth climbing, up to the galleries. The whispering gallery is so named because of the way a whisper will echo there. Higher still, there is access to the stone gallery on the exterior of the cathedral. At the very top is the Golden Gallery which has arguably the best view in London. The beautiful woodcarvings are the work of Grinling Gibbons and the exquisite ironwork is by Jean Tijou. Although in many ways a piece of history and a tourist attraction, the cathedral is still very much in use today. It is a national and international religious focus, a masterpiece of architecture and a centre of musical excellence. It was centre stage world-wide, through television, in 1981 for the fairytale marriage of Prince Charles and Lady Diana Spencer.
