1. Mine Casemate Marker

Inscription. The mine Casemate Building (located under this mound) was a concrete block building with a tile roof. This building housed the generators, storage batteries, and switches that electrically set off the mines in the shipping channel. A similar building was located at the south end of the island. To protect the building a mound of dirt was built over the western side. In 1920, protection was improved by encasing the whole building in a concrete box, eight feet thick, and covering it with the present mound of sand. Another building called the Loading Room was located across from the entrance to the Mine Casemate. Here the mine cases would receive their explosive charge.
