Well one ship that is not available in any form that I know of is the old ceremonial galley of the Doge of Venice. It was almost sacred - a deeply beloved and respected ship, called Bucentaur or
Bucintoro. It was used for the annual ceremony in which the Doge, on behalf of Venice, was married to the Ionian Sea. Napoleon burned it in 1798, when he took over the big Venetian naval base
Il Arsenale. There are still little bits and pieces in the Naval museum there, and a nice model, and it appeared in many paintings. the Venetians have a plan to rebuild it. See Wikipedia: Bucentaur
