Aztec Ruins National Monument (New Mexico)

… was proclaimed 92 years ago today (1923).

Aztec Ruins

Around 1100 A.D. ancient peoples embarked on an ambitious building project along the Animas River in northwestern New Mexico. Work gangs excavated, filled, and leveled more than two and a half acres of land. Masons laid out sandstone blocks in intricate patterns to form massive stone walls. Wood-workers cut and carried heavy log beams from mountain forests tens of miles away. In less than three decades they built a monumental “great house” three-stories high, longer than a football field, with perhaps 500-rooms including a ceremonial “great kiva” over 41-feet in diameter.

A short trail winds through this massive site offering a surprisingly intimate experience. Along the way visitors discover roofs built 880 years ago, original plaster walls, a reed mat left by the inhabitants, intriguing “T” shaped doorways, provocative north-facing corner doors, and more. The trail culminates with the reconstructed great kiva, a building that inherently inspires contemplation, wonder, and an ancient sense of sacredness.


Ancestral Puebloans related to those from the Chaco region farther south built an extensive community at this site beginning in the late 1000s A.D. Over the course of two centuries, the people built several multi-story structures called “great houses,” small residential pueblos, tri-wall kivas, great kivas, road segments, middens, and earthworks. The West Ruin, the remains of the largest structure that they built and which has since been partially excavated, had at least 450 interconnected rooms built around an open plaza. Several rooms contain the original wood used to build the roof. After living in the area about 200 years, the people left at about 1300 A.D.
