Theory: Layers and Preservation in an Archaeological Site

The name Uxmal is believed to originate from the archaic Mayan language phrase meaning "built three times."

Due to the fact that Uxmal was built on a core of concrete rather than plaster, it is well-preserved to this day compared to other Maya architecture of the time. One of the most prominent buildings, the Adivino - or Pyramid of the Magician - contains layers not only in its physical construction but in a conceptual sense as well. The pyramid is built in a stepped pyramid style with an oval or elliptical base, and unusual feature in Maya architecture at the time.

Another uncommon architectural aspect of the pyramid is the fact that it is built centered slightly to the east of the previous pyramid, rather than directly on top of the old site. It was typical in Maya architecture to layer one pyramid on top of an old one, however at Uxmal, the previous temple was preserved. The juxtapsition of the old and new pyramids allows for a simultaneous sense of renewal and preservation.
Layers existed within the design of other builds as well. In the Nunnery Quadrangle, for example, each individual building is built on a platform that is on a different elevation. This creates visual hierarchy through layers within the building.
The way Uxmal was constructed allows for a unique study of the site. Each layer can be studied and analyzed individually, and so the site as a whole can be considered both as a whole and separately.
