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?
Potala Palace in Tibet
The Sumela monastery in Turkey's black sea province of Trabzon
Mount Thor in Canada, featuring Earth's greatest vertical drop of 1,200 m (4,100 ft), with the cliff overhanging at an average angle of 105 degrees (15 degrees from vertical)
I particularly like the monastery - we need more places like this as adventure locations!
You may be interested in Paro Taktsang, or Tiger's Nest Monastery. I believe this was used in Batman Begins as the home base of the League of Shadows, before the villain turn.
