The story

How Washington came to be

From Wikipedia’s history of Washington.

Read it all →

Washington was founded as the Post of Opelousas in 1764 as a French trading post. In 1766, the first church, La Iglesia paroquial de la Immaculada Conception del Puesto de Opelousas, was established and the post later became known as Church Landing in 1822. In 1835, the town was incorporated under the current name.

In the early 1800s smaller steamboats started traveling up Bayou Teche to the Opelousas River, renamed Bayou Courtableau, at Barre’s Landing (named after Alexander Charles Barré) that became Port Barre, then to Washington where there was a bottleneck as the steamboats could not turn around. In 1848 Captain George W. Haygood completed a steamboat turnaround and Washington became an inland port.
