Lime and shell flattened: This structure shows a construction style based on earth covered with lime flattened, after which a thick layer of crushed shells in small fragments was placed. Lime in liquid form was poured over this layer, which was polished to obtain a smooth appearance. The polishing was not only decorative; it also served to seal the surface and prevent water from penetrating the earth cores.
