The Trinidad Valencera, fourth largest ship of the Spanish Armada, grounded and sank off the Donegal coast on 14 September 1588. Chronicle has followed the seven years' progress of archaeological work underwater which has revealed not the Trinidad Valencera herself, as yet, but the remains of a mighty army siege-train which was intended to batter down the gates of London. But who owns the Trinidad? The Venetians who built her, the Spanish who hi-jacked her, the English who sank her, the Irish in whose waters she lies, or the archaeologists from the City of Derry Sub-Aqua Club who found the wreck? And is the site a protected monument or a wreck? Andrew Faulds tells the story of this ship and its recovery, and the law, or lack of it, which puts at risk all historic wrecks round the coast of Britain and Ireland.
