St Paul's Cathedral - The Whispering Gallery
The Whispering Gallery is one of the most famous parts of the Cathedral. There are 257 steps up to the Whispering Gallery which is 112' (34m) above the floor of the Cathedral.
Although photography inside St Paul's is strictly prohibited, I managed to convince the press office to give me a photography pass for the day!
The Cathedral is the 2nd Largest in the UK (after Liverpool Anglican) and the 2nd Tallest (after Salisbury). The dome reaches 111m (365') above the Cathedral Floor
