One of the great attractions of the city is the Clock Tower. Well, clocks. The big clock and the astronomical clock, that is. This latter is somewhat reminiscent of the one in Prague (or vice versa) and is common to see many tourists waiting to watch the hours change. If you can, and it only happens on certain days of the year, don't miss the chance to climb the tower and see the inner workings. We were lucky that day and did. It's spectacular! It's never stopped functioning (except in cases of human error) since its construction and not many people knew how to get it started (finally, the got a farmer familiar with gear mechanics).
