Greenhouse site

The Greenhouse site is an archaeological site of the Troyville-Coles Creek culture in Avoyelles Parish, Louisiana.
Greenhouse is the most extensively excavated Troyville-Coles Creek site in Louisiana. The site consists of seven platform mounds surrounding a central plaza that measures by. Archaeologists have not found an associated village for the site, which supports the theory that the site was ceremonial in nature and that its builders lived elsewhere. Mound A, Mound E and Mound G are the 3 largest mounds at the site and form a triangle.
