Gilmerton Cove
Gilmerton Cove is a series of underground passageways and chambers hand-carved from sandstone located beneath the streets of Gilmerton, an ex-mining village, now a southeastern suburb of Edinburgh, Scotland. There has been much speculation about the origins of the Cove and its purpose.
The cove was restored and opened as a tourist attraction in 2003. It operated until the COVID-19 pandemic, and is closed as of 2023.
