Abo Elementary School (located entirely underground)

The former Abo Elementary School, located in Artesia, New Mexico, United States, has been identified by One Nation Underground (ISBN 0-8147-7522-5) as the first (and most likely only) public school constructed entirely underground and equipped to function as a fallout shelter. The school, completed in 1962, the year of the Cuban Missile Crisis, had a concrete slab roof which doubled as the school's playground. It contained a large storage facility with room for emergency rations and supplies for 2000 people in the event of nuclear warfare or other catastrophe. The building was listed on the National Register of Historic Places in 1999 and is located at 1802 W Centre Ave.
