Another great place to view the city. You’ll walk down a ramp, take some stairs down to the underground museum, ride an elevator to the observation deck, and climb some more stairs. All while learning a little bit of the Mexican history. Great city views once you get to the top observatory deck area. The historic part of this experience was also great. Once back on the street level, look carefully at the outdoor pillars that hold this structure. Each one holds the remains of an important Mexican historical figure including Pancho Villa. They have a small coffee shop at the top deck and a larger one on the first floor. No need for advanced ticket purchase. We purchased our tickets here.
