in accordance with the belief that if they are absent, the kingdom will fall. They are under the care of the Ravenmaster, one of the Yeoman Warders. As well as having ceremonial duties, the Yeoman Warders provide guided tours around the Tower. Garrison The Yeomen Warders provided the permanent garrison of the Tower, but the Constable of the Tower could call upon the men of the Tower Hamlets to supplement them when necessary. The Tower Hamlets, aka Tower Division of Middlesex's Ossulstone Hundred was an area, significantly larger than the modern London Borough of the same name, which owed military service to the Constable in his ex officio role as Lord Lieutenant of the Tower Hamlets. The earliest surviving reference to the inhabitants of the Tower Hamlets having a duty to provide a guard for the Tower of London is from 1554, during the reign of Mary I, but the relationship is thought to go back much further. Some believe the connection goes back to the time of the Conqueror. The duty is likely to have had its origin in the rights and obligations of the Manor of Stepney which covered most or all of the Hamlets area. Crown Jewels The tradition of housing the Crown Jewels in the Tower of London probably dates from the reign of Henry III (1216–1272). The Jewel House was built specifically to house the royal regalia, including jewels, plate, and symbols of royalty such as the crown, sceptre, and sword. When money needed to be raised, the treasure could be pawned by the monarch. The treasure allowed the monarch independence from the aristocracy and consequently was closely guarded. A new position for "keeper of the jewels, armouries and other things" was created, which was well rewarded; in the reign of Edward III (1327–1377) the holder was paid 12d a day. The position grew to include other duties including purchasing royal jewels, gold, and silver, and appointing royal goldsmiths and jewellers. In 1649, during the English Commonwealth following Charles I's execution, the contents of the Jewel House were disposed of along with other royal properties, as decreed by Cromwell. Metal items were sent to the Mint to be melted down and re-used, and the crowns were "totallie broken and defaced". When the monarchy was restored in 1660, the only surviving items of the coronation regalia were a 12th-century spoon and three ceremonial swords. (Some pieces
