Inside forgotten tomb shrouded in secrecy and buried beneath a picturesque hill

This is the forgotten Edinburgh tomb that has been shrouded in secrecy and buried beneath a picturesque hill.

Situated to the north of the City Observatory in the city, the burial chamber dates from 1795, and holds a secret.

It was only rediscovered and surveyed some 200 years later, prior to concealment after completion of drainage works.
