The old Maya ruins of Becán in México have quite a few things to recommend them. A number of structures have been restored, and are open to public viewing; several structures are both climbable and riddled with passageways (so many places to explore).

But really, the marquis attraction is this stucco figure of the Maya sun god Kinichná:

Since the stucco needs to be protected from the hot and humid environment (as well as from vandals), it’s in a purpose-built enclosure with a glass front. But the lighting’s tricky (no artificial light in the enclosure), and the glass is both dirty and scratched (take wet wipes and a paper towel) — so you have to work to get a decent shot of this bit of artwork…
