Tucked underneath a Liberton housing estate is a stunning real-life chamber of secrets, constructed in 1875.
What used to be the main source of Edinburgh’s water supply is described as half the area of Charlotte Square, though thankfully no Slytherin secrets were found in the tunnels. The beautifully built underground space served as a 15 million gallon tank, part of the Alnwickhill waterworks.
After the waterworks closed, many of the buildings were demolished to clear space for new homes - though the disused reservoir was preserved. After pictures were released, councillors had several ideas on uses for the space.
