Edinburgh has a fascinating ‘Underground City’, much of which is open to the public. It is made up of many different aspects, with a turbulent and intriguing past stretching back hundreds of years.

Features include hidden passages and cellars, ancient buried streets like Marlyn’s Wynd and Mary King’s Close (sealed after an outbreak of plague), castle dungeons and escape tunnels, a warren of vaults and chambers under Edinburgh’s mighty bridges, abandoned or repurposed rail tunnels, and anomalies like the strange subterranean dwelling of Gilmerton Cove.

Award-winning author and historian Jan-Andrew Henderson explores the legendary world beneath the streets and locations of Edinburgh in this pictorial guide.
