Pueblo Bonito

From AD 850 to 1250, Chaco was a hub of ceremony, trade, and administration for the prehistoric Four Corners area--unlike anything before or since.  Chaco is remarkable for its multi-storied public buildings, ceremonial buildings, and distinctive architecture.  These structures required considerable planning, designing, organizing of labor, and engineering to construct.  The Chacoan people combined many elements: pre-planned architectural designs, astronomical alignments, geometry, landscaping, and engineering to create an ancient urban center of spectacular public architecture--one that still awes and inspires us a thousand years later.
