Indian Temple Mound Museum
Run by the City of Fort Walton Beach, the Indian Temple Mound Museum houses a pre-Columbian mound. Despite being subject to over a millennium of erosion, the mound is 12 feet high and 223 feet wide at its base. Historians estimate that the mound was built around 850 AD by a Mississippian tribe as a ceremonial and political base for the tribe. In 1964, the site was designated a National Historic Landmark.
In addition to the mound, the museum houses pre-Columbian artifacts. Numerous archaeological projects have presented new information about the native population of Florida.
