For what I know (which isn’t much) there aren’t too many really old examples of western civilization in southern California. There was a really old Dunkin Donuts in my home town, but I don’t think anyone celebrated the building. So it’s a little hard for me to appreciate something like the Old Town Square astrological clock tower in the Czech Republic. That this clock tower in Prague is 600 years old is really cool, that they celebrated the 600th anniversary with a video mapping on the front of the building is even cooler. Check it out.
