A "Maya Snake Dynasty Temple"
with some (rather rectangular) restoration going on, it looks like.
Would there be some Serpent Stacking visible where the stonework is untouched so far?
My eye is drawn to a couple places:
“Xunantunich’s name means "Stone Woman" in the Maya language (Mopan and Yucatec combination name), and, like many names given to Maya archaeological sites, is a modern name; the ancient name is currently unknown. The "Stone Woman" refers to the ghost of a woman claimed by several people to inhabit the site, beginning in 1892. She is dressed completely in white, and has fire-red glowing eyes. She generally appears in front of "El Castillo", ascends the stone stairs, and disappears into a stone wall.” ~ https://en.wikipedia.org/wiki/Xunantunich
