D&D General Real life 'dungeons' you can visit

[Marc_C]

In 2012 while on vacation in Budapest I discovered the Budavari Labirintus. A complex of natural caverns under the castle on the Buda side of the city. It was fun to visit.

The Labyrinth is a highly protected natural cave. The half a million year old cave flight systems, isolated from each other, but situated on the same level, had begun to be connected by the inhabitants of surrounding villages from the 13th century. Then on, this interoprable cave system, functioned as a wine cellar in peacetime and during the wars was used as a shelter. During the 1930s the Labyrinth was a tourist attraction, but operated as a shelter during the Second World War. The first Waxworks in Hungary, was operating here from 1984 – 1996. The place was closed from 1997 – 2011, but has been welcoming visitors again, from November 2011.

Years back I visited the Forestiere Underground Gardens in Fresno, CA – the creation of Baldassare Forestiere. Probably the most uplifting "dungeon" I've explored: Forestiere Underground Gardens

Quinta da Regaleira in Portugal has a superb garden with caverns and a stairwell that goes down into the ground. Some buildings are linked by underground passages. I actually 'disappeared' from my wife's view only to 'reappear' behind her using the chapel tunnel. A very roguish move!

The Sintra castles region is a full day excursion. Bring water.

The catacombs of Rome are almost the perfect example of course. A maze of tunnels and stairways, full of ancient graves that were used for rituals by obscure secretive religious sects (ie, Christians...)

The Naracoorte caves are a lesser-known one in my part of the world. Not a maze exactly, but a startlingly large and spectacular underground complex full of hundreds of skeletons of huge extinct creatures, that long ago fell down sinkholes and couldn't get out.

Naracoorte, where half a million years of biodiversity and climate history are trapped in caves

The ruins on the Palatine Hill in Rome (really the entire area around the old Forum), have a strong "open air" dungeon vibe.

For a more contemporary locale, Every time I visit Chicago I'm struck by how layered a city can be, with these underground sections that feel like modern labyrinths.

Chislehurst Caves in SE London. They combine Celtic, Roman and Saxon chalk mines in a massive system. They are allegedly haunted and were also used as a mass air raid shelter in WW2. Both Hendrix and the Stones (who are from nearby Dartford) played gigs their in the 1960s in the famous “raves in the caves.”
An awesome real dungeon:
