Greenhouse site

The Greenhouse site (16 AV 2) is an archaeological site of the Troyville-Coles Creek culture (400 to 1000 CE) 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 200 ft by 350 ft. 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 (12 ft in height, with a base 120 ft square and a summit 80 ft square), Mound E (10 ft in height, with a base 120 ft square and a summit 80 ft square) and Mound G are the 3 largest mounds at the site and form a triangle.
