Heart of Midlothian Mosaic

The Heart of Midlothian is a heart-shaped mosaic formed of red and grey granite stones set directly into the pavement of the Royal Mile, just outside the west door of Saint Giles' Cathedral. It marks the exact location where the door to the Old Tolbooth once stood. For centuries, this building served as the administrative center, courthouse, and primary prison for Edinburgh, gaining a dark reputation for its overcrowded and unsanitary conditions.
