Pretty cool, huh? This Temple of Santiago, also called Quechula, emerges every so often from a reservoir created by a dam in the late 1960s. It was abandoned in the late 1700s due to a plague, but was constructed by a heroic friar who exposed and fought against colonial slavery. Also pretty cool. I'd tell you all about it, but you can read it all right here. Of course, the gamer in me knows this place is just full of treasure and, probably, supernatural guardians. Thanks Connor McAnally for the link!
