The most imposing collection of remains to date, delineates a building 12.5 meters by 6 meters with a Northwest division. The foundation is of impressive size, a meter wide at the opening, and shows occasional sunken areas thought to be foundational corner posts.

Unfortunately, we do not know what the completed building looked like.
