SS Selma is one of Galveston Bay's odder landmarks: a concrete-hulled tanker launched near the end of the First World War and later scuttled offshore after damage made repairs impractical. Its long, low remains sit in the water as a reminder of an experimental moment in shipbuilding.
You do not visit it like a museum, and access depends on viewpoints or boat trips rather than walking up to a sign. Still, it is a worthwhile curiosity for travelers who like maritime history, especially when paired with Galveston's port, railroad, and seaport museum stories.
