Buckingham Palace has 775 rooms. These include 19 State rooms, 52 Royal and guest bedrooms, 188 staff bedrooms, 92 offices and 78 bathrooms. In measurements, the building is 108 metres long across the front, 120 metres deep (including the central quadrangle) and 24 metres high.
The role of the Beefeaters is to guard any prisoners in the Tower of London, and to protect the most valuable items in the Tower – the Crown Jewels. This job has diminished over time though, as the Tower no longer holds prisoners and the security systems surrounding the Crown Jewels have become very sophisticated. The change in the Beefeaters’ job started when the Royal Family moved out of the Tower of London during the reign of the Tudors.
