The largest pyramid in the Western Hemisphere and the third largest in the world, the imposing Pyramid of the Sun towers 66 meters tall, a monumental site that dwarfs even the Pyramid of the Moon. Built around 100 CE from red volcanic rock, when Teotihuacan was reaching its zenith, the base measures 220 by 230 meters.

On the pyramid’s west side, there are 248 steps leading to the top of the structure, although visitors can no longer climb it. It is thought that there was once a temple at the summit – the Aztecs later used it for rituals and sacrifices.
