Walking around old town of Prague can be quite rewarding if you like street photography. There are interesting people, tourists, political rallies, musicians and many others. It's never boring.

One thing I have to say I like about the Czechs. They know how to play up to tourists. The old city hall tower has an observation deck, which is accessible and the views are stunning. Now, all the German towns and cities also had towers with observation decks. The only difference is that the Czechs were smart, and installed a nice elevator in the tower, Germans are a little more primitive, and if one wanted to see the top, one had to use the old way of climbing, namely stairs.
