The Pyramid of the Moon is a large pyramid located in the ancient city of Teotihuacan, Mexico. It is the second-largest pyramid in the city, standing at about 43 meters (141 feet) tall. The pyramid was constructed around 200 AD and is aligned with the nearby Pyramid of the Sun and the Avenue of the Dead, which is the main thoroughfare of Teotihuacan. The structure is built in several stages, featuring a series of platforms and terraces. Archaeological studies suggest that the Pyramid of the Moon was used for religious ceremonies, including rituals dedicated to the goddess of the moon. Its impressive size and design reflect the architectural skills of the ancient Mesoamerican civilization.
