Ruderi del Castello di Cairo
The castle of the Del Carrettos was built by Otto I, the son of Enrico I, the founder of the noble lineage. According to legend, in 1213 St. Francis of Assisi, heading for Spain, stopped at the castle and healed the deaf and dumb daughter of the marquis. From 1268, to the court of the castle there came minstrels and troubadours from around Europe, among them the Provençal poet Rambald, mentioned by Dante in the Divine Comedy as Arnaldo. In the 17th century the castle was destroyed during the wars that involved the Gonzagas, France, the Republic of Genoa and Spain.
