Bank. From 1963, the Bank Picquet travelled by vehicle clad in service dress and armed with automatic weapons, with the emphasis on security moving from ceremonial to tactical deployment. Improved security features and armed police made the guard unnecessary, and the service ended on the evening of 31 July 1973. Windsor One of the public duties battalions or incremental companies is responsible for providing the Windsor Castle Guard. The location of the ceremony at Windsor varies; in the Easter, when the King is in residence it usually takes place on the lawn in the castle's quadrangle. In wet weather or winter, to protect the lawn, or when the King is not holding court at Windsor Castle, the ceremony occurs outside the guardroom by Henry VIII's Gateway at the foot of Castle Hill. The ceremony for changing the Windsor Guard is broadly the same as that which takes place at Buckingham Palace. At 10:40 am, the new guard marches from Victoria Barracks, through Windsor and turns left, going up Castle Hill to enter the Lower Ward. During Easter, and when the King is holding court at the castle, the guards change in the Upper Ward on the grass. When changing guard in the normal way, the new guard arrives at roughly 11 am when the old guard has formed up outside the guardroom. Once both guards and the duty band (there is no duty band on Sundays) are present, the old guard and new guard will present arms to each other, interspersed by bugle calls – the officers will then go towards each other and symbolically touch left hands to 'hand over the keys to the castle (though no actual keys are handed over anymore). The guards will then slope arms and the reliefs will be formed up to go around the castle and change the sentries – during this process, the band typically plays a selection of music. Once the relief returns, the old guard forms back up ready to march back to Victoria Barracks. The band leads them out whilst the new guard presents arms. Once the old guard has left, the new guard is dismissed to the guardroom where they will be based for the next 24/48 hours – every two hours, the guard relief will march out and change the sentries. Edinburgh Sentry posts are mounted at Palace of Holyroodhouse and at Edinburgh Castle. Although the Household
