Buildings date from the 18th century to the early 20th century.","why_significant":"The plazas have been the hub of San Antonio since the 18th century, from the Spanish presidio and the Canary Island settlers' town to a center of city and county government and banking. The varied buildings show the city's growth from presidio to frontier town to commercial center. The nomination values the district for this diversity of styles and periods rather than uniform design.","narrative":"Downtown San Antonio's Main Plaza and Military Plaza have been the city's central gathering places since the 1720s. Military Plaza began in 1722 as a parade ground and market for Spanish soldiers, and it still holds the Spanish Governor's Palace. Main Plaza was settled in 1731 by Canary Island families who built homes around a village church and the Casas Reales. Over time the area shifted toward commerce and government. The district takes in thirteen whole blocks plus parts of two others, with 36 contributing buildings. They include the Italian Renaissance Revival City Hall, the Romanesque Revival Bexar County Courthouse, San Fernando Cathedral, the twelve-story Main Plaza Building of 1922, and many two- and three-story masonry commercial blocks. The Melchoir de la Garza house, from about 1800, is the last of the small homes that once ringed the plazas. The nomination values the district for its variety of styles and eras, with city business, banking, worship and government still drawing people to the plazas.","period_of_significance":null,"architect_builder":"Otto Kramer (City Hall); James Riely Gordon (Bexar County Courthouse); Alfred Giles (Wolfson Building, Old Bexar County Jail); Francis Giraud (San Fernando Cathedral); J.P.
