The HAC will be firing a 62-gun salute by the Tower of London, to mark the anniversary of the Queen's Coronation in 1953.
Where is the best place to watch this event from?
if you can't get there early enough for a spot at the front then it's probably on the Tower Bridge roadway. I don't know if you know that stretch of river by the Tower, but they hold the crowd back by the restaurant on the waterfront (just past the shop). You can watch it from inside the Tower as well, if you get up on the curtain wall. But of course you'll have to pay to get inside.
