It contains Mississippian-period ceremonial mounds, a colonial trading post site, an earthlodge, an 1856 farmhouse, a Civil War earthwork and an Art Moderne visitor center begun in 1938.","why_significant":"Smithsonian archeologists who excavated the site in the 1930s judged it one of the most important archeological centers east of the Appalachians, with evidence of about 10,000 years of human use and a chronology still used as a basis for southern prehistory. It also holds a rare colonial trading post site, the Dunlap house and Civil War earthwork, and a visitor center noted for its Art Moderne design.","narrative":"Ocmulgee National Monument preserves a large archeological landscape on a bluff above the Ocmulgee River, east of Macon, Georgia. Seven rectangular Mississippian-period mounds form its core, joined by a separate Lamar area with two later mounds. Excavations in the 1930s recovered over a million pottery and flint artifacts and revealed a sequence of six prehistoric levels of occupation. An earthlodge with a restored clay floor dates to about A.D. 1015. The site also holds the outline of a colonial trading post occupied from roughly 1690 to 1715, the 1856 Dunlap house, and an earthwork tied to the 1864 Stoneman raid on Macon. A 1938 Art Moderne visitor center, decorated with a frieze copied from Lamar pottery, serves as museum, offices and research storage. Smithsonian specialists considered the complex among the most important archeological centers east of the Appalachians, which underlies its protection.","period_of_significance":null,"architect_builder":null,"architectural_style":"Art Moderne (Visitor Center); ante-bellum frame farmhouse (Dunlap House)","criteria":[],"status_note":"Publicly owned national monument open to visitors; the mounds are grassed over and accessible by steps, the earthlodge is restored, and the Dunlap House has served as the superintendent's residence.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:41.049635-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_GA/66000099.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000099/2944e77051-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000099/2944e77051-1600.webp","licence":"CC BY-SA 3.0","author":"Bubba73 (talk), Jud McCranie","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:OcmulgeeLargeMound.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:OcmulgeeLargeMound.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/93207073","wikipedia":"https://en.wikipedia.org/wiki/Ocmulgee_Mounds_National_Historical_Park","wikidata":"https://www.wikidata.org/wiki/Q1517500"},"indexable":true,"url":"https://nationalhistoricalregister.com/georgia/bibb-county/ocmulgee-national-monument-66000099/"}
