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 feet (61 m) by 350 feet (110 m). 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 feet (3.7 m) in height, with a base 120 feet (37 m) square and a summit 80 feet (24 m) square), Mound E (10 feet (3.0 m) in height, with a base 120 feet (37 m) square and a summit 80 feet (24 m) square) and Mound G are the 3 largest mounds at the site and form a triangle.
