At the southern end of the Clatsop Plains lies a town at the very edge of the Pacific, the city of Seaside.
Seaside began as a historic salt-making site, having finally reached the ocean by the Lewis and Clark expedition in 1806. This location would later become a full-fledged coastal resort by 1899. By 1912, Franco-Prussian War veteran Alexandre Gilbert moved to the area from San Francisco with big ideas in mind for this little vacation community. Gilbert, a natural at real estate development, decided to donate one and a half miles of his land to create a public network to unite the many cottages and resorts. This stretch of land would later be known as one of Seaside’s most famous landmarks today, the Promenade, or just the “Prom,” for short.
