|Sir Christofer Wren designed the classical St. Paul's Catedral. The golden cross surmounting it is 110m above the ground and the golden ball on which the cross rest measures 2m in diametrer. In the interior of the dome is the Whispering Gallery where a whisper can be heard clearly on the opposite site. From the Whispering Gallery a steep climb leads to the Stone Gallery, opening onto a panoramic view of London. On the top of the inner dome is the Inner Golden Gallery, from with one can have an even more spectacular view of the city.
