So this is it. London's most important site. Built by William the Conqueror to show his power to the natives, and used as a fortress,palace, treasure house and prison for seven or eight hundered years.

This is the view as you approach the tower. In front is the moat, which was joined to the river. Unfortunatley, seeing as one of the Thames's many uses was as a sewer (as well as drinking water supply), the moat became an enormous cesspit. According to our guide, that is why the grass is so green. They got the Dutch in to fix it - they know all about controlling water, of course.
This is Traitor's Gate,
the main entrance to the tower from the water. Here was where traitors were brought in. Thomas More came in here, sent by by Henry VIII Elizabeth came though those gates, sent by her half-sister Mary I. Elizabth's mother, Anne Boleyn, was executed here, as was her aunt, Catherine Howard.
The RackGuy Fawkes was tortured on a rack like this, here in The Tower.
A BeefeaterHe was our guide, and he was terrific. An old army bloke complete with Sargeant-Major voice and Sargeant-Major moustache.
The White Tower, the original tower that gives the fortress its name, and the central keep in the middle of the complex. This is the most recognisable part. Inside now is some of the Royal Armoury.
This is the Bloody Tower,
where 'Those bastards in the Tower' were kept, giving Shakespeare's Richard III sleepless nights. They were his nephews, and a threat to his position. 'Shall I be plain? I wish the bastards dead.' Murdured here? Probably, I reckon. Walter Raleigh also lived here, in considerable comfort. His wife and kids lived with him. Of course one needs one's domestic staff. He grew tabacco (our guide has still not forgiven him for introducing to this to Britain along with potatoes)in the garden.

The Crown Jewels are in this building on the left. You aren't allowed to take photos. So here are some from the net:
The Imperial State Crown with Cullinan II
The Queen's Mum's Crown with Kohinoor.
The Sovereign's Sceptre with Cullinan I.
We weren't as impressed as we thought be would be. Sure there's a hell of a lot of diamonds and what-not - 2,868 diamonds on the Imperial crown alone, and gold and stuff of course. Oh and the Star of Africa (Cullinan I), largest gem quality diamond in the world, and Koh-i-Noor, another big one, been famous for 400 years or so. But you get wizzed past on travelators, so you look at things for 30 seconds, then away. Just a bunch of pretty silly looking shiny stuff, really. After reading up bit it's more interesting, but the time we didn't know anything about the jewels. Did you know that when the Cullinan Diamond was brought to Africa, a fake was put on a ship with armed Police etc, and the real one was sent by post.
Poignant monument
on the spot where poor old Anne Boleyn (and others) died.
Inside the White Tower: The ArmouriesHere's some amazing armour of Henry VIII and horse.
Henry's Melee armour
Note extraordinary cod-piece arangement.
So that was the Tower of London, for me, the most essential thing to see in London.
Oh, and here's Alice:
