I applied for free tickets to witness "The Ceremony of Keys" that takes place each night in the Tower of London. According to the website, the ceremony of locking up the Tower has taken place each night for over 700 years. I'm not sure exactly what will happen. But it sounds like a cool thing to see and the tickets are free. You just have to mail a request with a self addressed envelope into their office two months in advance. Only 15 people get to watch this ceremony each night, so that's pretty cool too!
