I’ve just found out that tickets to the Ceremony of the Keys at the Tower of London are Free. The Ceremony of the Keys is the ritual of locking up the Tower of London (containing the Crown Jewels) each night and has taken place every night without fail for more than 700 years!
To get tickets you have to write to:
Ceremony of the Keys Office
Tower of London
LONDON, EC3N 4AB
And include the following:
Names of all attendees
Two possible dates you can attend for at least two months in advance (three months in advance if you wish to attend in July or August)
A self-addressed envelope together with the requisite British postage stamps, or a minimum of two ‘Coupon-response international’. Please note that American or other non-British stamps are not valid in the UK.
This is a great opportunity to really experience a moment of British Heritage.
