El Infiernito, (Spanish for "Little hell"), is a pre-Columbian Muisca site located in the outskirts of Villa de Leyva, Boyacá Department, Colombia. It is composed of several earthworks surrounding a setting of menhirs (upright standing stones); several burial mounds are also present. The site was a center of religious ceremonies and spiritual purification rites, and also served as a rudimentary astronomical observatory.
