For a far better grounding in the Mayan history of the region than you can get at El Baúl, head to the Finca Las Ilusiones, also a one-time sugarcane plantation. The site is officially known as the Museo de Cultura Cotzumalguapa, and takes in a collection of stelae and stones gathered from nearby archaeological sites. Most of these come from Bilbao, on the northern edge of Santa Lucía, which housed a collection of carved stones. The 80-ton, so-called Monument 21 remains
at the Bilbao site, and has been copied in fiberglass for display at this museum. The remainder of the Bilbao stones here are authentic.
