On 2 December 1797, after the French established their domination in Italy, the town became part of the "Department of the Gulf of Venus", with the capital in La Spezia, in the Ligurian Republic annexed to the First French Empire. From 28 April 1798 with the new French law, the territory of Portovenere fell in the seventh canton, as the capital, the Jurisdiction of the Gulf of Venus since 1803 and the main center of the third State of the Gulf of Venus in the jurisdiction of the Gulf of Venus. From 13 June 1805 to 1814 it was included in the Department of the Apennines. It was at this point which, in 1812, it became part of the coastal route called "Route Napoleon" in honor of the French general and now known as localized road 530, which still connects the marine center with La Spezia via Fezzano, Le Grazie and Terizzo.
