It has the dubious honor of imprisoning Mary, Queen of Scots in 1567. Though she eventually escaped, she never saw Scotland again.
We left Edinburgh on Day 3 of the trip, via the Forth Road Bridge. There are three bridges spanning the Forth. The bridge to our left is a cable-stayed bridge called Queensferry Crossing, scheduled to open May 2017. The one to our right is a railway bridge which has been in use since 1890, and you can see the lovely rock at its northern end in the last photo.
