St Paul's Cathedral, designed by court architect Sir Christopher Wren and was completed in 1710. Its famous dome is one of the largest in the world, measuring 111.3 meters in height and is part of London's iconic skyline. San Pablo is one of the places where events of national importance are held. The funeral of Lord Nelson, the Duke of Wellington and Sir Winston Churchill took place in the Cathedral, Prince Charles married Lady Diana Spencer and, more recently, the Queen celebrates her Golden Jubilee and the 80 th anniversary with thanksgiving service in this place of worship. Over the years, the decoration was added and removed, so that today the nation's history can be seen in mosaics and stone sculptures throughout the building. The Whispering Gallery runs around the inside of the dome is 259 steps from the ground surface fascinates children and adults, because a whisper against its walls can be heard on the opposite side.
