Almost all of it was built between 1929 and 1932 as a new Army Air Corps flying training field.","why_significant":"The nomination presents Randolph Field as a planned 'Air City' with a circular road layout that was the first and only one of its kind on an American military airfield. It also highlights the cohesive Spanish Colonial Revival buildings, Art Deco hangars, designed landscaping and high integrity. The district has 350 contributing resources and 47 noncontributing ones.","narrative":"Randolph Field is a military flying-school campus at the center of Randolph Air Force Base, about 18 miles northeast of San Antonio, Texas. Nearly all of it was built between 1929 and 1932 for the Army Air Corps. Its plan, called the 'Air City,' arranges roads in concentric circles and octagons around a central officers' club, with eight roads radiating outward like spokes. Hangar lines run along two sides of a larger square, aligned with the prevailing southeast winds. Most buildings are Spanish Colonial Revival, with stucco walls over hollow tile and red clay tile roofs, while the hangars are Art Deco. Many followed Quartermaster Corps standard plans, though major buildings such as the Administration Building, with its domed water tower, were designed locally. The district contains 350 contributing and 47 noncontributing resources, and its layout and landscaping remain largely intact despite window replacements and enclosed porches. It remains an active air facility.","period_of_significance":null,"architect_builder":"Standardized plans by the Army Quartermaster Corps; prominent buildings by local architects; Lieutenant Clark planned the Administration Building; Captain N.
