At the entrance of the theatre, there are mascarons in bronze with depictions of Tlaloc, and Chaac, the Aztec and Maya deities of water, which along with the rest were designed by Gianette Fiorenzo. On the arch over the stage there are representations of various mythological personas such as the Muses with Apollo. This was constructed in Hungary in the workshops of Géza Maróti. However, the most impacting aspect is the stage "curtain" which is a stained glass foldable panel created out of nearly a million pieces of iridescent colored glass by Tiffany's in New York. This stage curtain is the only one of its type in any opera house in the world and weighs 24 tons. The design of the curtain has the volcanos Popocatépetl and Iztaccíhuatl in the center. Around them is a Mexican landscape surrounded by images of sculptures from Yautepec and Oaxaca. This design was inspired by work done by artist Gerardo Murillo (Dr. Atl). The theatre has a capacity of 1,000.
