Last night I went to The Tower of London to witness the longest-surviving ceremony anywhere in the world... The Ceremony of The Keys. This locking-up of ritual has been taking place EVERY night, without fail, for over 700 years.
Halt! Who goes there? The Keys. Whose keys? The Queen's keys (etc.)
I remember doing a project on it when at junior school after a school trip. Which reminds me that in all my school years, excluding art trips in the 6th form, I can only recall ever going to three places; The Tower of London, London Zoo and Lullingstone Roman Villa...
The ceremony is free to attend but you have to apply here.
I haven't been to the Tower for a proper visit in decades, so another look around is well overdue, but I am not sure that this is the year to go, what with the Olympics and all the extra visitors headed this way. I'll just have to add it to my ever-lengthening list...
Here are some other London keys and keyholes:
Top: Holloway, Smithfield, Fleet St, Spitalfields
Middle: Finsbury Park (x2), Bloomsbury, Covent Garden
Bottom: Bloomsbury, Soho, Holloway, Kentish Town
