Fort Polk (1846-1850) - A mexican village developed on this point, settled by mexican ranchers in the 1700's. The village was abandoned prior to the U.S. Declaration of war with Mexico in 1846. U.S. Forces led by General Zachary Taylor occupied the point on 24 Mar 1846. Taylor erected a depot here to receive supplies from New Orleans. The six-sided Fort, named for President Polk, consisted of 4 sides of earthen embankments and 2 sides open to the shoreline.

Fort Polk was garrisoned from 1848 until 1850 by Capt. F. C. Hunt's company of the 4th Artillery regiment. By January 1849 the buildings were being moved to different locations on the Rio Grande. On February 9, 1850, the post was abandoned but the settlement it attracted eventually developed into Port Isabel. The location was used as a transit depot for materials for Fort Brown in 1852, and on February 21, 1861, at the outbreak of the Civil War, it was seized by a Confederate artillery company from Galveston.

Remnants of the Fort were visible until the 1920's but the U.S. Army Corps of Engineers straightened the channel and installed jetties in the pass, obliterating the site of both the Mexican fort at Brazos Santiago and Fort Polk.

Location: County Hwy. 100, about a block from the western end of the causeway which links the town of Port Isabel with South Padre Island, Port Isabel Lighthouse State Park, Port Isabel, Cameron County, Texas
