Great place to visit. I recommend to buy the Classic Pass online (at least one day in advance). Explore the gardens, palace (audio guide included) and Gloriette :)
A wedding cake made of marble. The dazzling façade, fully detailed with prehispanic motives and greek muses... The interior... Pure art deco... Amazing. The murals from Rivera, and Orozco... And the fabulous tiffany courtain from the stage... Wow
