Originally exploited by the Romans, the Salina Turda Salt Mine’s history dates back to at least the middle of the 13th century. And even as a mine, it was a fairly sustainable operation given that no mechanical devices were ever used to cut the salt clods harvested, nor were dynamites exploded. After a series of takeovers, the mine was shut down, but opened again as a tourism destination in 1992.

This is an excellent site for Nolan – not just because it’s a cool set in itself that needs very little intervention – but also because it has a stable microclimate. Temperatures remain steady at between 11 and 12 degrees Celsius, though at 75-80%, humidity levels are usually pretty high. And we couldn’t help but notice that the cave is in Transylvania, a cozy spot for bloodsucking vampires. With his new green cape, Batman is sure to prevail.
