Beneath a scaled down Mayan pyramid (http://maps.secondlife.com/secondlife/SLB%20Astonish/132/165/23), Instituto Espanol this year brings us Hidden Worlds: Sacred Cenotes of Chichén Itzá. If I remember correctly, this is the same group who last year brought us a very interesting immersive exhibit on Aztec afterlife mythology. (Takeaway, dying in Aztec times was not for wimps.)
This year they take us on a journey into a cenote, a flooded underground chamber. Once you climb down the entrance, you can collect some free dive gear and get wet. As you swim around the underwater caverns, a few more interpretive signs tell about archeological discoveries in one particular Cenote, some rather grim.
It’s hinted that there is A) an exit and that B) they hope you find it. I didn’t. I climbed back out the way I came in. However I think this is entirely fair as one of the earlier notes mentioned that the cenote in question has a single entrance!
I always love learning new things, so this sort of exhibit automatically appeals to me. In one place I’m exposed to some Mesoamerican history (in which I readily admit I’m sadly deficient) and a bit of Mayan art.
