Three panels are located on the Harford Pier outline the history of Port San Luis.

Port San Luis - A Gateway Through Time Geology

Bays are formed over thousands of years by erosion. Less resistant rock is weathered away by waves over time to form the bay. More resistant rock around the edges of the bay result in headlands, projections of land around the bay into the larger body of water.
Port San Luis - A Gateway Through Time Fishing and Boating

In the 1500s and 1600s the Port San Luis area was visited by Spanish and Portuguese explorers. Following a bustling period as a trade and passenger port in the late 1800s and early 1900s, the Port today supports local fishing and boating ventures.
Port San Luis - A Gateway Through Time Commerce

By the 1880s Port San Luis served as the gateway for shipping goods and moving passengers to and from the Pacific Rim and Europe. The Port developed into the largest crude oil shipping port in the world by WWII. Today, the Port is used mainly for commercial and sport fishing and other recreational purposes.
