Blackness Castle is a 15th-century fortress on the south shore of the Firth of Forth. It was built, probably on the site of an earlier fort, by Sir George Crichton in the 1440s. At this time, Blackness was the main port serving the Royal Burgh of Linlithgow, one of the main residences of the Scottish monarch. The castle, together with the Crichton lands, passed to James II of Scotland in 1453, and the castle has been crown property ever since. It served as a state prison, holding such prisoners as Cardinal Beaton and the 6th Earl of Angus.
Strengthened by Sir James Hamilton of Finnart in the mid-16th century, the castle became one of the most advanced artillery fortifications of its time in Scotland. A century later, these defences were not enough to prevent Blackness falling to Oliver Cromwell's army in 1650. Some years after the siege, the castle was repaired, and again served as a prison and a minor garrison. In 1693, the spur protecting the gate was heightened, and the Stern Tower shortened as a base for three heavy guns. Barracks and officers' quarters were added in the 1870s, when the castle was used as an ammunition depot, until 1912. The castle was briefly reused by the army during World War I. It is now a Scheduled Ancient Monument, in the care of Historic Scotland.
The castle stands on a rocky spit in the Firth of Forth, and is oriented north-south. The castle comprises a curtain wall, with integrated north and south towers, and a separate central tower in the courtyard. To the south-west, a defensive spur forms the main entrance, while a water gate to the north-west gives access to the 19th-century pier. Outside the walls are 19th-century soldiers' barracks and officers' quarters. The castle is said in popular legend to have a ley tunnel linking it with the House of the Binns, which lies about 3.1 km to the south.

Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
