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.
The first mass-production process for making steel was invented by Englishman Henry Bessemer. Rejected by the British his process was adopted by the German gunmaker Alfred Krupp, who became the most advanced armaments manufacturer in Europe.
