Castle Dunbar represents the ruins of one of the most powerful Scottish fortresses. Castle stands above the modern port town of Dunbar, East Lothian. On this territory there lived an ancient Celtic tribe of varadinov, founded in the late fifth century their Kingdom from Gododdin. The geographic name "Dunbar" refers to the brythonic language. In the VII century, when the territory of modern South-East Scotland and North East England formed the Anglo-Saxon Kingdom of Bernicia, Dunbar castle was already built and served as an important strategic point.

During the early middle Ages the castle of Dunbar belonged to the vassals of the kings of Northumbria. In 678 year in prison of the castle was kept by St. Wilfrid, Archbishop of York, exiled king of Northumbria by Agricom. In the ninth century, the castle was burnt by the king of Scotland Kenneth I.
The first stone of the present building of the castle was built by one of the last of the counts of Northumbria by Gospatric about 1070. After the Norman conquest Gospatric had to flee from England and he found refuge with the king of Scotland Malcolm III granted him lands in Mercia and the castle of Dunbar.

The castle belonged to the Earls of Dunbar several centuries, until in 1457 it was destroyed to prevent its capture by the British. At the beginning of the XVI century it was restored by the king of Scotland James IV and transferred to the Duke of Albany. At the same time was completed Western Bastion. In 1548 the castle was burned by the Earl of Shrewsbury, but quickly restored, and in the 60-ies of the XVI century during the Anglo-Scottish wars it contained French garrison.
