Charles bridge - Prague's famous landmark - is 650 years today. Emperor Charles IV started the construction with the first stone on July 9, 1347 at 5:31 am (I don't know how they know it so exactly).
There were celebrations, of course. But as we have national holidays on Thursday and Friday I think there were only tourist here celebrating while all Praguers were out of Prague :)
