Visit to explore with your Tower of London tickets. The tower has been everything from royal residence to mint, menagerie, armory, observatory and the holding place for the Crown Jewels – a function it still serves.
Obviously you'll want to check out all that royal bling, but there's plenty more to see.
The White Tower holds, among other things, Henry VIII's XXXL suit of armor in the Royal Armouries collection. St John's Chapel, on the first floor, dates back to 1080, making it the oldest church in London!
