Main and Military Plazas Historic District
Also known as: See Also:70000741; 75001956; 75001949; 77001426
Why it's listed
Downtown San Antonio's Main Plaza and Military Plaza form a district of thirteen full blocks plus parts of two more, holding 36 contributing buildings. Military Plaza began in 1722 as a parade ground and market for Spanish soldiers, and still has the 1740 Spanish Governor's Palace, now a city museum. Main Plaza was laid out for the Canary Island families who founded the town in 1731. Around the plazas, small houses gave way after the Civil War to two- and three-story masonry commercial buildings. Civic landmarks include the Italian Renaissance Revival City Hall (1888-91), the Romanesque Revival Bexar County Courthouse and San Fernando Cathedral. Early twentieth-century additions include the twelve-story Main Plaza Building of 1922 and the eight-story Rand Building. The district was listed because it shows more than 200 years of San Antonio's growth in one place. Its value rests on this variety of styles and periods, and the plazas remain the center of business, banking and government.
Significance in brief: The two plazas have been the hub of San Antonio since the 18th century, from the 1722 Spanish presidio parade ground and the 1731 Canary Islander settlement to later city and county government and banking. The varied buildings show the city's growth from Spanish presidio to cattle-era town to commercial center. Its architectural importance lies in this diversity rather than in a uniform style.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
