Coat of Arms of San Antonio, Texas.  The two-part shield is surmounted by a castle coronet, representing the municipality.  On the left is the coat of arms of Saint Anthony of Padua, the son of a Portuguese nobleman.  The "T," or Tau cross, indicates that Anthony was a priest.  The ermine tails dotting the lower left were on the coat of arms of the saint's father.  On the right side of the shield, a red background, or field, represents the blood shed for Texas’ liberty.  The star represents the Republic and State of Texas.  The Battle of the Alamo is represented by the former mission church.  The Latin Libertatis Cunabula means "Cradle of Liberty."  

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 City Council of San Antonio adopted the coat of arms on February 17, 1972.
