The arrival of King Charles II of England in Rotterdam, may 24 1660

HMY Mary was the first Royal Yacht of the Royal Navy. She was built in 1660 by the Dutch East India Company. Then she was purchased by the City of Amsterdam and given to King Charles II, on the restoration of the monarchy, as part of the Dutch Gift. She struck rocks off Anglesey in thick fog on 25 March 1675 while en route from Dublin to Chester. Although 39 of 74 crew and passengers managed to get to safety, the wreck quickly broke up. The remains (bronze cannon) were independently discovered by two different diving groups in July 1971. After looters started to remove guns from the site, a rescue operation was organized and the remaining guns and other artefacts were taken to the Merseyside Museums for conservation and display. After the passing of the Protection of Wrecks Act 1973, she was designated as a protected site on 20 January 1974.
