The Tower of London has been home to many important national institutions for over 900 years. Close to the seat of royal power at Westminster, the fortress offered a secure site for a variety of functions vital to England’s monarchy.
Competition for space and power grew as the number of institutions expanded and their employees increased. While some organisations moved out and other functions ceased, many operated for hundreds of years, making the Tower England’s ultimate power house.
In WW I Germany built the longest-range gun ever. Its 100kg projectile travelled 122km, and left the muzzle at 1500 metres per second and reached a height of around 40km. About 6 times faster and higher than an average transatlantic passenger jet.
