Built around 1365, as 'the King's Privy Wardrobe' to safeguard Edward III's personal treasures. Today you can explore inside to see where once royal treasures were locked away in wooden chests and records of the House of Lords were stored on parchment rolls. Although there have been alterations over the years, the tower still bears the imprint of stonemasons, carpenters, leadworkers and tilers who worked together building the tower. It's one of only two buildings from the medieval Palace of Westminster to survive the fire of 1834. Conjure up the past in rooms which re-create the lives of a medieval treasury official and an 18th-century clerk. Take in displays covering all three floors, highlighting the tower's history and its changing roles over the centuries. Enjoy remarkable medieval features, including the sculped roof vaults.
