      Heart of Midlothian The 'Heart 
      of Midlothian' is a heart-shaped mosaic in the cobbled pavement close to 
      the NW corner of St Giles Church in the High Street, part of Edinburgh's 
      Royal Mile. It marks the 
      centre of the Old Town of Edinburgh, the spot where the C15 Tolbooth 
      prison stood before being demolished in 1817. |
