I visited the Tower of London in January 2009 and was amazed by it. The tower, being close to 1000 years old is in much greater shape than the Angkorwatt temples that I had visited around the same age. The tower affords some wonderful views of the Thames River and also some skyscrapers in the surroundings. I got in for only 8 pounds because I have a coupon that gives 50% reduction in admission fees.
