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 the Seawall Boulevard, this structure created an entirely new tourism industry that buoyed the city's economy through war, the Great Depression and hurricanes.  These fifteen historic postcards, excerpted from Galveston Sewall Chronicles, by Kimber Fountain, provide a glimpse into the unbreakable spirit of Galveston's resilient population.
