Construction began in 1876 under contractor Ed Braden and Company.","why_significant":"The nomination argues that the Quadrangle has been the symbol and focal point of military operations in Texas and the Southwest since 1879. It served as a Quartermaster Depot and later as headquarters for army commands. Events tied to it include the 1886 detention of Geronimo and the 1898 outfitting of the Rough Riders.","narrative":"Built from 1876, the Quadrangle at Fort Sam Houston in San Antonio began as a Quartermaster Depot. Ed Braden and Company built the U-shaped rubble limestone complex with a tin roof around a central courtyard, and the original contract price of $83,900 rose to a final cost of about $98,367. A water and watch tower in the courtyard was converted to a clock tower in 1882 and holds a stone tablet reading \"In Peace Prepare for War.\" The district covers about 8.8 acres, including the tower, water tanks and small sentry and storage buildings. General Ord took command in 1879. The post later hosted the Apache leader Geronimo in 1886, supplied the Rough Riders in 1898, and served as headquarters for Army commands, including Fifth Army from 1971. It has been altered with modern utilities and added windows but keeps its original character. It remains in military use.","period_of_significance":"19th and 20th centuries (construction begun 1876)","architect_builder":"Ed Braden and Company (contractor); Captain George W.
