Discover the stories and personalities behind the major organisations of state, who took care of royal business behind the mighty Tower walls, from 1100 to the present day, in a new permanent exhibition in the White Tower.
The exhibition, curated by the Royal Armouries, showcases the roles of the major organisations that provided the bedrock of England’s power throughout the centuries.
Great institutions include the Ordnance Office, Ordnance Survey, the Royal Mint, Record Office, the Jewel House, Menagerie and Royal Observatory. Power House will also put the spotlight on other Tower of London functions, ranging from royal residence to state prison.
The phrase "Lock, stock and barrel" refers to something in its entirety, the whole thing – in the same way that a complete gun has a lock, a stock and a barrel.
