Bridge of Sighs
The main entrance is approached by a bridge over what was then the Molendinar Burn. The bridge, which was designed by David Hamilton was completed in 1836. It became known as the "Bridge of Sighs" because it was part of the route of funeral processions (the name is an allusion to the Bridge of Sighs in Venice). The ornate gates (by both David and James Hamilton) were erected in 1838, restricting access onto the bridge.
