King's Magazine
Fort Frederica National Monument: The Magazine. James Olgethorpe built a fort on the Frederica River in 1736, garrisoned by Highland troops and his own 42nd Regiment of Foot. Therein lay a key purpose of the fortified settlement. The British wanted to prevent the Spanish from moving north from Florida into Georgia and the Carolinas. An expedition was sent against the Spanish at St. Augustine in 1740 and a Spanish attack repulsed in 1742.

Today the powder magazine, consisting of two brick-vaulted rooms 38 feet long, is the only remaining portion of the south section. Only wall stubs remain in the northern half. The King's Magazine served as the entryway to the fort complex, storage for gun powder, offices and prison".
