The Lighthouse Ruins is a mythical location in Grand Theft Auto: San Andreas.
Description[]
Located near the Bayside Marina, there is a small peninsula jutting out into the bay, with very steep seaside cliffs on all sides. At the peak of the cliffside, there is a small, flat, circular structure that resembles the foundation of a lighthouse.
It has been theorized that there was originally a lighthouse on the peninsula in the beta, but it was removed from the final version of the game for unknown reasons. Players believe that it would have been difficult for game developers to remove the lighthouse's foundation from the terrain, so they just left it there.
Another theory is that this lighthouse is a reference to Alcatraz, a prison also existing in the beta game.
A Skimmer spawns next to the peninsula, which could be a hint to what the structure's purpose was in the game.
The supposed lighthouse is also believed by fans to be the foundation of an artillery piece, as it has the same appearance, and the location on the western borders of the map is very similar to the United State's artillery positions on their western borders facing the Pacific Ocean. The Cold War is canon within the GTA series, so this could be truthful as GTA San Andreas is only set one year after the fall of the Soviet Union, and the United States' defense could still be active at the time.
