In the 1800s, the low-lying Texas coast made charting a seagoing course extremely difficult, and a number of captains requested that something be done. The Port Isabel Lighthouse was constructed in 1852, near sites of Civil War Battle of Palmito Ranch (1865) and Mexican War Battles of Palo Alto and Resaca de la Palma.
