Via Caracciolo is named after the distinguished Neapolitan admiral Francesco Caracciolo (1752-1799), whose story is still kept alive in the popular imagination (at least, this is the impression I get after reading Luciano de Crescenzo).
In the aftermath of a French invasion in 1799, Caracciolo joined the Republicans who wished to depose the Bourbon King Ferdinand IV, who was allied to the British. Admiral Nelson, who was carrying on a menage-a-trois liason with the Hamiltons in Naples, just managed to rescue the royal family from Naples before the city fell to French invaders. Despite an amnesty having been granted the revolutionaries, Nelson stated that an amnesty could be authorised only by King Ferdinand, and he declared it invalid. Caracciolo and the others were handed over to the Royalists for execution, and he was hanged as a common criminal from the main-mast of his ship, the Minerva.
