Now hard to believe, Eilean Donan Castle was once one of the largest castles in the west Highlands, known to have featured seven towers, the remains of which lie buried on the island. This book provides a refreshed view of the lost medieval guise of the castle, of its 13th-century origins and form, and of who was responsible for building it, allowing the castle to be positioned accurately in the complex dynamics of powerholding and display of the earls of Ross and associated militarised kindreds of the west Highlands during six centuries of change up to the castle's destruction in 1719. A new history and the details of the below-ground archaeology allow us to see the lost medieval castle in our mind's eye 500 years after it vanished. Focusing on the wealth of archaeological material unearthed during the campaign shows the castle hosted master craftspeople including goldsmiths, shipwrights and hereditary swordsmiths. Exquisite personal items, decorative mail armour and weapons, musical instruments, gaming pieces, imported pottery and animal bones bring the castle and its inhabitants back to life.
