Караларские каменоломни, Catacombs in Crimea
The Karalarskiye Kamenolomni are expansive catacombs and a stone quarry.
These quarries date back to the 1st century AD, primarily used for mining limestone.
The stone from Karalarskiye Kamenolomni has been pivotal in Crimean architecture.
Part of the quarries can be visited with guided tours.
Over 20 kilometers of labyrinthine tunnels form an underground city.
