The Edinburgh Vaults

The Edinburgh Vaults (commonly known as the South Bridge Vaults) are an extensive subterranean labyrinth comprising approximately 120 stone chambers integrated inside the 19 massive masonry arches of the South Bridge viaduct in the Old Town of Edinburgh, Scotland, United Kingdom. Completed in the late 18th century to span the steep Cowgate ravine, the interior chambers were originally engineered as commercial storerooms and workshops. Rapidly rendered unlivable by catastrophic water infiltration, the vaults devolved into notorious subterranean slums, were abandoned and sealed in the mid-19th century, and lay forgotten for over a century. Since their rediscovery in the 1980s, the complex has gained international infamy as one of Europe's most prominent paranormal and dark-tourism hotspots.
