Fewkes Group Archaeological Site (40 WM 1), also known as the Boiling Springs Site, is a pre American history Native American archaeological site located in the city of Brentwood, in Williamson County, Tennessee. It is in Primm Historic Park on the grounds of Boiling Spring Academy, a historic schoolhouse established in 1830. The 15-acre site consists of the remains of a late Mississippian culture mound complex and village roughly dating to 1050-1475 AD. The site, which sits on the western bank of the Little Harpeth River, has five mounds, some used for burial and others, including the largest, were ceremonial platform mounds. The village was abandoned for unknown reasons around 1450. The site is named in honor of Dr. J. Walter Fewkes, the Chief of the Bureau of American Ethnology in 1920, who had visited the site and recognized its potential.
While it was partially excavated by the landowner in 1895, archaeologist William E. Myer directed a second, more thorough excavation in October 1920. The report of his findings was published in the Bureau of American Ethnology's Forty-First Annual Report. Many of the artifacts recovered from the site are now housed at the Smithsonian Institution. It was added to the National Register of Historic Places on April 21, 1980, as NRIS number 80003880.
