About Brazos Santiago Entrance Range Rear Lighthouse

This 22-meter steel skeletal tower, painted red with a white vertical stripe, serves as the rear range light for Brazos Santiago Entrance. Supported by piles on a square platform, it carries a rectangular daymark. Its green light flashes once every 6 seconds, visible only when ships are aligned with the range. The structure was moved 530 meters east between 2024 and 2025. The site is open to visitors, though the tower itself remains closed to the public.

Why it matters: This range light is indispensable for safe navigation into Brazos Santiago, specifically guiding vessels along a precise course where its green light is exclusively visible. Its relocation in 2024-25 highlights the dynamic nature of coastal waterways and the continuous effort required to maintain accurate navigational aids.
