Beneath the bustling streets of Edinburgh, Scotland, lies a secret world known as the "Edinburgh Vaults." These hidden chambers are tucked away beneath the arches of the South Bridge, a massive 19th-century structure towering over the city's historic Old Town. Originally constructed in the late 18th century, the Vaults served as storage spaces and workshops for local merchants before falling into neglect. Over time, they became a refuge for outlaws, wanderers, and the city's most impoverished residents. Nowadays, the Edinburgh Vaults draw in curious tourists eager to delve into the city's past as they wander through the underground passageways.
