This is the cover sheet for the Historic American Buildings Survey of Mission of San Gregoiro de Abó. The top of the sheet includes a side view of the mission. A map to the mission appears at the bottom. The sheet also includes the following introductory information about the mission:The Mission of San Gregoiro de Abó, built in the late 1620's, is one of four missions built in the Salinas province of early Spanish colonization in New Mexico which today comprise Salinas National Monument. The three other missions are La Purisma Conception de Cuarac, San Buenaventura, and San Isidro.
The site of Abó was a thriving pueblo community at the time Franciscans began to convert the resident Tompiro Indians in 1622, but was abandoned between 1672 and 1678.
The mission is notable for the construction method using buttresses to support relatively thin walls, a method used in European church architecture. San Gregoiro de Abó is the only example of the use of this method for a seventeennth-century New Mexican church.
