The Maya site known for its Pyramid of the Magician is Uxmal.
Uxmal is an ancient Maya city in the Puuc region of Mexico's Yucatán Peninsula. The Pyramid of the Magician, also called the Pyramid of the Dwarf or Adivino, is the site's most recognizable monument and its tallest structure. Unlike the more commonly straight-sided Maya pyramids, it has an unusual rounded or elliptical plan and a distinctive steep profile.
The pyramid was built in several stages, with construction beginning as early as the sixth century and later additions continuing through the Classic period. Maya builders commonly enlarged important temples by placing new structures over earlier ones; at Uxmal, multiple construction phases remain visible in the monument's layered form. The city flourished particularly between about AD 600 and 1000.
Its popular name comes from a Yucatec Maya legend about a magically gifted dwarf who built the pyramid in a single night and became ruler of Uxmal. That story explains the modern nickname, not the archaeological construction process. The other options are major Maya sites, but none is associated with this monument: Chichen Itza is known for El Castillo, while Tikal and Palenque have different signature temples.
