If you live in Tower Hamlets (and only if you live in Tower Hamlets, sorry the rest of you), then the next three days provide a great opportunity for you to check out one of London's great tourist sites - the mighty Tower of London.
Now most of you probably have a job (take an extended lunch) but if not, until Wednesday, you have the option of visiting the Tower for £1. In order to claim your cheap entry, you just have to take along a Tower Hamlets leisure card or a library card.
The Tower is open from 9am and last entry is at 5pm. From Thursday entry is normal price and tickets can be bought for £15.00.
