The “marquis” structure at the ancient Maya ruins of Chichén Itzá, El Castillo (a.k.a. the Pyramid of Kukulkan):

What most tourist brochure photos don’t show you, though, are its two faces.  The pyramid’s north and west sides have been fully restored (so, look as close to “new” as we can get), while the south and east sides have just been consolidated and stabilized (and so, look rougher).  In the shot above, north is to the right — the pyramid’s north face is what you’ll most often see on postcards and such.
