Yeomen Warders
In the 21st century, tourism is the Tower's primary role, with the remaining routine military activities, under the Royal Logistic Corps, having wound down in the latter half of the 20th century and moved out of the castle. However, the Tower is still home to the regimental headquarters of the Royal Regiment of Fusiliers, and the museum dedicated to it and its predecessor, the Royal Fusiliers. Also, a detachment of the unit providing the Queen's Guard at Buckingham Palace still mounts a guard at the Tower, and with the Yeomen Warders, takes part in the Ceremony of the Keys each day. On several occasions through the year gun salutes are fired from the Tower by the Honourable Artillery Company, these consist of 62 rounds for royal occasions, and 41 on other occasions.
