The Pyramid of the Moon is the second largest pyramid in Teotihuacan, Mexico. Locals called it Tenan, which in Nahuatl, means “mother or protective stone.” The Pyramid of the Moon sits atop a structure that is older than the largest pyramid in Teotihuacan, the Pyramid of the Sun.

The Pyramid of the Moon is thought to have been constructed between 200 and 450 AD. A platform atop the pyramid was used to conduct ceremonies in honor of the Great Goddess of Teotihuacan, the goddess of water, fertility, the earth, and creation. This high platform and the sculpture found at the bottom of the pyramid are dedicated to The Great Goddess. A slope on the pyramid in front of the staircase gives access to the Avenue of the Dead, the main road which travels through the ancient city.
