The lighthouse marks the midpoint of Torre del Mar's seafront and the symbolic divide between Poniente (west) and Levante (east). Built in the late 19th century and still operating, it's one of the most photographed corners of town — especially at sunset when the white tower catches the sunset light against the dark sand below.
You can't go inside, but the surrounding plaza has benches, palm trees and one of the better viewpoints over the bay.
