The murals here, by O. Barry Cunningham, are among the finest in Mexico. The architecture is beautiful as well. It's free and nobody seems to mind the tourists wandering around with their mouths agape.
Over the years I have worked with several officials in Aguascalientes - the Palacio is where things happen. It is built around a courtyard with murals around the inside walls. The big plaza is also a place for many things to happen in this city.
