Statement of Significance (as of designation - June 13, 1962):
The ruins here represent an important period in Southwestern history. Mission La Purisima Concepcion de Cuarac was built in 1629 and abandoned in 1674. The pueblo and mission here help to document the early period of Pueblo-Spanish contact. As the ecclesiastical headquarters of the Inquisition in New Mexico, they also played an important role in the controversies between Church and State of the 1600s.
