Lecco has 47,000 inhabitants and is the capital of the province of Lecco. It lies at the end of the south-eastern branch of Lake Como (the branch named Lake of Lecco). The Prealps rise to the north and east, cut through by the Valsassina of which Lecco marks the southern end. The lake narrows to form the river Adda, so bridges were built to improve road communications with Como and Milan.
