1. Waverley Vaults
The vast ad labyrinthine Waverley vaults were built during the redevelopment of Waverley Station by the North British Railway Company in the mid-1890s. Previously used for storage by nearby traders at Market Street, the vaults, which effectively support a large section of Waverley Station, now lie mostly empty and unused. Photo: Colin Hattersley
2. Alnwickhill Waterworks
Situated below homes at Liberton Gardens and Alnwickhill Road, the giant brick-built storage tank at Alnwickhill Waterworks dates back to 1875. Covering a space around half the size of Charlotte Square, the 15-million gallon tank once stored the city's water. Photo: Contributed
3. Mary King's Close
Four centuries ago the once densely-populated Mary King’s Close would have been open to the skies. In 1753 a number of streets and houses were deemed uninhabitable, and were cleared and covered over for the Royal Exchange. The resulting network of underground streets and homes is now a top city tourist attraction. Photo: Lisa Ferguson
4. Scotland Street Tunnel
The mile-long Scotland Street Tunnel once formed a rail link directly under the New Town between Waverley Station and Canonmills. It was abandoned in 1868 after just 21 years of operation and has been mostly closed off to the public ever since. Photo: Unknown
