In 1742 it was the headquarters of the forces that turned back a Spanish invasion during the War of Jenkin's Ear, and the Battle of Bloody Marsh was a major factor in halting that attempt. It was also a planned community where the Wesley brothers preached.","narrative":"Fort Frederica National Monument on St. Simons Island, Georgia, preserves the remains of a fortified colonial town founded in 1736. The listed area includes tabby and brick foundations of houses, two storehouses, the King's Magazine, the Barracks ruins, a burial ground, the town moat and earthworks built in 1736 and 1739. It also covers the eight-acre Bloody Marsh Battle Site, five miles to the southeast. Frederica served as the hub of Georgia's defense against Spain. In 1742 it was headquarters for the forces that turned back a Spanish invasion during the War of Jenkin's Ear, and the fight at Bloody Marsh helped halt the advance. At its peak the town held about 1,500 people, including skilled craftsmen and soldiers of Oglethorpe's regiment. John and Charles Wesley preached there. After the regiment disbanded in 1749 and a fire in 1758, the soldiers withdrew in 1763 and the site was abandoned.","period_of_significance":"18th Century","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Publicly owned and preserved by the National Park Service as a national monument with unrestricted public access; the structures are mostly foundations, ruins and earthworks, in unaltered condition on the original site.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:40.967473-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_GA/66000065.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/100005351/e5720d746f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/100005351/e5720d746f-1600.webp","licence":"CC BY-SA 3.0","author":"Bubba73 (talk), Jud McCranie","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:FortFredBackside.jpg\" rel=\"noopener\">Bubba73 (talk), Jud McCranie</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:FortFredBackside.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/93208425","wikipedia":"https://en.wikipedia.org/wiki/Fort_Frederica_National_Monument","wikidata":"https://www.wikidata.org/wiki/Q1438527"},"indexable":true,"url":"https://nationalhistoricalregister.com/georgia/glynn-county/fort-frederica-national-monument-boundary-increase-additional-documentation-100005351/"}
