There was an interesting thread where photos of each state's capitol building were posted. Some capitols were really impressive and most thought Texas had the most attractive capitol building.
How about each city's own city halls? Do you have photos you can share?
I live in metro Los Angeles so I am posting a photo of the LA city hall but also the Pasadena city hall [the city I live in].
