St. Paul's Cathedral is one of London 's most awe-inspiring sights. Wren's original design for rebuilding. St Paul's was based on High Renaissance ideas, but it was considered too Italianate and too modern.

The marvellous choir stalls and organ case near John Donne's tomb were carved by Grinling Gibbson as part of Wren's original decorative scheme. Next it is best to visit the crypt, with Waren's actual tomb, a simple black slab, and an audio-visual programme explaining the history and construction of the building, from the laying of the foundation stone in 1675 to the placing of the last stone on the lantern above the dome in 1708. The crypt itself is massive, extending beneath nearly the whole of the church. After the descent into the crypt the next and most exciting part is the ascent to the dome. There are 256 steps to the Whispering Gallery. The circular gallery carries sound round so that someone standing on the opposite side will hear your whispers quite clearly after several seconds' delay.

Sir Christopher Wren's masterpiece, has played important role in royal life  over the centuries. Queen Victoria celebrated her Diamond Jubilee in St. Paul's in 1897 and the marriage of Prince Charles and Princess Diana was also celebrated there.  On 4 June 2002, the National Service of Thanksgiving at the Cathedral celebrated the current Queen Elizabeth II's Golden Jubilee.
