Caption: Battery Construction No. 129 Marker
Additional Description: Captions: (bottom left) Battery No. 129 diagram; (3 upper left) Gun barrel in San Francisco on it's way to the Marin Headlands. When work on Battery Construction No. 129 was stopped, the gun barrels had been transported to the site. The weapons were never installed and the barrels lay stored in the tunnel until 1948 when they were cut up for scrap.; Embedded in the the walls of the tunnel, you can see the rings through which cables would have been run to maneuver the gun barrels into the emplacement.; To hide the tunnel entrances, and the gun openings, iron rings were embedded into the surrounding concrete to secure camouflage nets. Had the battery been given a name, it would have been placed above the tunnel entrance - the rectangular insert in the concrete was designed for that purpose.; (map, lower right) The two gun positions on the seaward side of this hill were perched 800 feet above sea level, making this the highest coast artillery battery in the country.
