Let's share some fantastic, bizarre, and weird real world locations that would make perfect fodder for #ttrpg !
My own contribution is "Christ of the Abyss", a bronze statue of Jesus that was deliberately sunk into the ocean off the coast of Italy in 1954. Two other statues were cast from the same mold later on, and sunk at Grenada and Florida.
I find the very concept of religious statues being sunk into the ocean fascinating - and, of course, in fantastic worlds people might have an easier time visiting such statues. Perhaps they have acquired some magic that allows them to breathe water for some time, or perhaps they are naturally amphibious. Or natural water breathers - perhaps there is some trade deal with surface dwellers where land-based religious items are created for aquatic civilizations that they cannot manufacture themselves.
What other such weird locations do you know of?
Another one: The "Bergpark Wilhelmshöhe" in Kassel, Germany.
This is a masterpiece of Baroque landscape architecture, and the Hessian landgrave at the time was only able to afford it because his father sold of Hessian subjects to the British so that they could put a stop to those pesky rebels in the North American colonies. The park is built across a hill slope (and covers an elevation change of more than 250 meters). Its highlights are the "Wasserspiele" ("Water Plays"). On every Sunday and Wednesday during the warmer seasons, water is released from a vast cistern at the top, located beneath a giant bronze statue of Hercules. Over the course of 75 minutes, this water flows down a series of artificial waterfalls and channels until it powers a giant fountain close to the bottom of the park.
Beyond that, the park has all sorts of other attractions - a fake ruined castle, a fake ruined Roman aqueduct, and a series of miniature temples to assorted Roman gods. This park makes a perfect setting for all sorts of cinematic adventures and/or occult weirdness!
