Fodor's Expert Review Fort Frederica National Monument

Built by English troops in the mid-1730s, Fort Frederica was constructed to protect the southern flank of the new Georgia colony against a Spanish invasion from Florida. At its peak in the 1740s, it was the most elaborate British fortification in North America. Around the fort today are the foundations of homes and shops and the partial ruins of the tabby barracks and magazine.
