Pwll Fanog wreck

The Pwll Fanog wreck is a small Medieval-era wooden vessel that sank in the Menai Strait, off the coast of Anglesey in Wales. The cargo vessel, believed to date to the later half of the 16th century, was carrying hand-worked slates which came to rest on top of the vessel itself when it sank. The site was discovered in 1976 during a marine biological survey; it was designated under the Protection of Wrecks Act in 1978 and is a protected wreck managed by Cadw.
