Buckingham Palace is one of the most famous buildings in the world. Full of chandeliers and massive rooms, the 775-room Palace is associated with being the heart of the monarchy, even if a monarch does not currently live there.

While many tourists visit the Palace each year, few know everything that goes on behind closed doors, especially when it comes to the lives of the staff who call the Palace home. However, one man who does know is former royal butler, Paul Burrell.

Before serving as Diana, Princess of Wales' butler for a decade before her death, he served the late Queen Elizabeth II.
