Around the Catedral Metropolitana one can find "shamans" cleansing away evil spirits (for $10 MEX, of course) or troops of Aztec dancers providing great entertainment for the throngs of tourists who visit the Centro Histórico in downtown Mexico City. A visit to the Zocalo is mandatory for any number of reasons. Art and architectural reach their zenith in the urban center. For those just interested in people watching, the Zocalo offers a bit of everything from local characters to organized demonstrations. Day or night something is going on!
