Coat of Arms of Bexar County, Texas.  Represented at the upper left are the arms of Don Alvaro de Zuniga, Duke of Bexar in Spain, including the gold chains of Navarre, which in Spain corresponded to today's United States Medal of Honor.  At upper right, Mission San Francisco de Espada represents the works of the Spanish missionaries.  The eagle on the lower left represents both the Aztec eagle of Mexico and the American bald eagle.  At lower right, the cannon represents the battles for independence of the Republic of Texas as well as the Texan support of the Confederacy in the Civil War.  The coronet surmounting the quadrants of the shield represents a duke of Spain.

The coat of arms was designed by Thomas A. Wilson and illustrated by Ramon Vasquez y Sanchez, with the cooperation and approval of the Spanish government and appropriate organizations in both Texas and Spain.  The Bexar County Commissioner's Court adopted the coat of arms for the county of Bexar on December 22, 1971.
