Le Roi de Rome was named after the son of Emperor Napoleon I, born in 1811. It is not the replica of a ship that actually existed but an arsenal model built before the prince's birth and re-used as a gift on that occasion. At the time, arsenal models were important during the ship-building process. Outstanding craftsmanship, attention to detail, and original rigging and sails increase the singularity and value of this model of a ship with two decks and 80 cannons. Borda and Sané developed this class of warship in the late 18th century, a period marked by France's rivalry with England and its famous Royal Navy. It was armed for six months, carried a 900-man crew and had a capacity of 3,870 barrels.
