I visited this site in mid October 2002 during a brief official visit from the USA. Waited for just 5 minutes to get into Westminster Abbey. This site is a masterpiece with the tombs of Kings and Queens. The history dates back to 11th century! William the Conquerer's coronation was held in the Norman Abbey at 1066! The rose windows were very impressive. A definite must visit in London. Do go inside and explore. Worth every penny of the 6.00 pound entry fee.
