Blackness Castle
Blackness castle once guarded the village of Blackness when it was the seaport of Linlithgow. This is a 15th century keep and courtyard castle . In 1537 work began to thicken the exposed walls with provision for defending guns which transformed Blackness into one of the most effective artillery fortifications in Scotland. It was besieged and damaged by Cromwell but repaired by Charles II. In the 17th century the keep was used as a prison for some of the distinguished Covenanters until 1707. From 1870 -74 it was converted into an ammunition depot.
