Lecco is located on the eastern branch of Como Lake, on the left bank of Adda River. Famous for being the place where writer Alessandro Manzoni set the novel I Promessi Sposi: Lecchese cultural identity is witnessed by interesting historical-literary itinerary on the traces of places that inspired the great novelist. Included from 2007 in Regio Insubrica and strategic crossroads for Valtellina, Lecco became increasingly important during Middle Ages when, following Peace of Constance, it was annexed to Ducato of Milan which conferred on it current urban layout characterized by porticoes and elegant palaces. Lecco, between the nineteenth and twentieth centuries, became one of the first industrial centers in Italy to be known as "Iron City". Numerous religious and civil buildings to be visited: Basilica of San Nicolò, with adjacent bell tower of the city, Palazzo delle Paure, Ponte Azzone Visconti, Medieval Tower, Theater of the Society and amous Villa Manzoni, declared in 1940 National Monument by King Vittorio Emanuele III together with the former Convent of Capuchins.
