Mansfield Cut Underwater Archeological District

Off Port Mansfield near Padre Island, this underwater district preserves the remains of three Spanish shipwrecks from a 1554 fleet disaster in the Gulf of Mexico. Four Spanish naos sailed from San Juan de Ulúa for Havana carrying precious metals and other cargo, but a storm drove them across the Gulf and three ran aground off the Texas coast with about 300 people aboard. Salvage recovered about half the cargo that summer. The wrecks—Santa Maria de Yciar, Espíritu Santo, and San Esteban—form a major record of early Spanish seafaring and colonial trade on the Texas coast, and their modern rediscovery and protection helped shape Texas underwater archaeology law and policy.
