The Tower of London
(Nearest tube is Tower Hill which is in the Circle/yellow line and the District/Green line) is one of my favourite historic places.
There are free tours by the Yeoman (who are all ex military) the tours are every 30 minutes where you can meet them near the entrance. Every tour, you can learn something new of historical significance.
There are also audio guides available - again included in your entry ticket.
A former Royal residence, Prison, Zoo, Treasury and execution site of;
Queen Anne Boleyn, Catherine Howard and Lady Jane Grey.
The Crown Jewels are also kept at the Tower.
There is a cafe called the Armoury-where you can buy hot food and cakes.
A bowl of soup is ÂŁ7.50 and a slice of Victoria sponge ÂŁ6.00.
There is nowhere within the Tower that you can have a picnic. There are eateries nearby that are quite reasonably priced.
Tower bridge is next to the Tower-check out the lift times on your visit-it’s a remarkable engineering site.
