Along Galveston's Gulf Coast runs a seventeen-foot-high, ten-mile-long protective barrier--a response to the nation's all-time deadliest natural disaster. The seawall remains a stoic protector more than a century later, shielding the island from much more than physical destruction. As the foundation of Seawall Boulevard, this structure created an entirely new tourism industry that buoyed the city's economy through war, the Great Depression and hurricanes. Adapting to the cultural trends and political movements that defined the past century, the seawall represents the unbreakable spirit of Galveston's resilient population and provides a fascinating glimpse into bygone times.
