Fort Prince Frederick was the southernmost fort in British North America from 1726 to 1758. Initially constructed of logs, it was later improved with tabby walls, which were completed in 1733. After the founding of Georgia on February 12, 1733 several other forts were constructed farther south, including Fort Frederica on St. Simons Island, diminishing the strategic importance of Fort Frederick. The fort is located in Port Royal, South Carolina.
