Prince Antonio Pignatelli, 6th Prince of Belmonte by marriage and a Prince of the Holy Roman Empire, minted his own coinage among which was the famous "zecchino of Belmonte", a gold coin on which appears both the Prince's head and coat of arms. In 1806 and 1807 Belmonte supported Amantea and Fiumefreddo while under siege by French troops commanded by General Peyri. Belmonte's castle was the last to surrender. Under the French, Belmonte became the centre of the administrative area of Crati, comprising the territory that reaches from Amantea to Guardia Piemontese and including the cities of Aiello, Altilia, Mangone and Rogliano. With the proclamation of the Kingdom of Italy in the late 19th century, Belmonte gained the additional name of Calabro, to distinguish it from other Italian places of the same name.
