Casa Rinconada

Casa Rinconada is an Ancestral Puebloan archaeological site located atop a ridge adjacent to a small rincon across from Pueblo Bonito in Chaco Culture National Historical Park, northwestern New Mexico, United States.

There is also an unusual 39 foot (12 m) long underground passage, perhaps used in the ceremonies to allow performers sudden entry thus surprising the audience.

Casa Rinconada was excavated in 1930-31 by archaeologists Vivian and Reiter and the University of New Mexico/School of American Research field schools.

It was reconstructed in part by Vivian in 1933, while Richter of the National Park Service worked on capping outer walls in 1955.

With a diameter of 64 feet (20 m), Casa Rinconada is the largest excavated great kiva in Chaco Canyon.
