The historic mine storeroom at Gulf Islands National Seashore will be transformed into a dining and exhibit area to serve visitors arriving by ferry. Adapting this structure fulfills the National Park Service's mission to preserve resources for public education and inspiration. The mine storeroom was originally built in 1901 to store underwater mines for defending Fort Pickens against enemy ships. After the fort's decommissioning, the building was used for maintenance and storage. Its rehabilitation will enhance public understanding of the area's coastal defense history.
