As you leave the museum grounds, you walk between two cut-back walls of adobe blocks. These are actually the interior fill of a gigantic U-shaped Platform that surrounds the Sun Pyramid on the east, west, and south sides. One hundred years ago the path you are on served as the as the bed for a small railroad constructed by Leopoldo Batres to haul out the excess dirt from his Sun Pyramid excavation!
