This 1852 lighthouse, which helped guide ships through Brazos Santiago Pass to Point Isabel until 1905, now affords panoramic views of Port Isabel, South Padre Island, and as far as the eye can see out over the Gulf of Mexico. Also on Lighthouse Square is a recently constructed replica of the lighthouse keeper's cottage made from the 1850 blueprints for the original. The lighthouse and cottage are part of a $2.5 million restoration project currently underway.
