The name 'Fino Mornasco' derives from two different Latin words: fines (boundary land) and Mornascorum (owing to the fact that the region was dotted with mills in the past). The latter, in particular, was added by Royal Decree in 1863 in order to distinguish the Fino located in the Province of Como from the one lying in Bergamo. Stone tablets with Etruscan inscriptions have been found in the area; but it was in Roman times that Fino gained in importance, being run through by an important Roman street: the one from Milan to Chiavenna (pass Lake Como) and from here on, forking, to the Spluga and Maloja passes. Fino and its territory were also called 'Prato pagano' (heathen field). As a matter of fact, after the Edict of Constantine, in which Christianity was officially recognised, Como embraced the new religion and persecuted all non-Christians (heathens) who eventually took refuge in Fino.

Monuments:
Parish church of St. Stefano - It is probably an early Christian church, although it has been much altered over the centuries. The present structure dates from the 1950'. Little remains of the earlier building, most notably a wall fragment with interesting frescoes from the early 16th century. In front of the church stands a War Memorial. In the surrounds, there are the most important villas in Fino.
Villa Odescalchi Raimondi Tagliaferri - It is a Baroque building modified by Simone Cantoni at the beginning of 1800. The unsuccessful marriage of Giuseppe Garibaldi and Giuseppina Raimondi was celebrated here.
Villa Mambretti - Later Villa Baserga. Designed by Federico Frigerio and built in the 1920-30, this villa is rather eclectic in style and features coeval decorations and material coming from the church of the Crocifisso in Morbegno. The building, which now houses the Town Council, is surrounded by a large park.
