People have lived in Lake Como since prehistoric times as it played an important part in the communications of settlers living between northern and southern regions. When the Romans took over the area, they built the Via Regina (Queen Teodolinda Road) which is the same road used today on the West coast of the lake in order to connect Italia with Raetia (a province of Rome which would geographically correspond to modern day Switzerland, SW Germany and W Austria). Lake Como was a very affluent area in Roman times (under the emperor Augustus) as it became an important trade connection between the Po Valley (the location of modern-day Milan) and the Rhine Valley in the north (modern-day Germany) thanks to the passes in Switzerland which enabled travelers to cross the Alps.

The village is certainly of Roman origin, as it owes its’ name to the consul Publio Cesio Archigene. Argegno has Roman origins, as they seem to demonstrate two tombstones found in Brienno, referred to Roman Publius Cesium Archigenes instructed to erect altars to the gods, from whom it seems to derive the name of the village. Set in a point of considerable strategic importance, the town has been since antiquity a fortified part of a wider defense system which extended as far as Lenno and the Isola Comacina to obstruct the passage of invaders. The ancient centre of the village is very picturesque. With the fall of Rome and the subsequent geopolitical instability in Italy a series of fortifications were constructed in the medieval period, including the arched bridge which still stands.

In the Middle Age there were erected two castles. One of these, built in 1270 by followers of the Guelfi Vittani Antonio Castle was a stronghold in bloody battles against the Ghibellines Rusconi. This work is mentioned in the eleventh and twelfth centuries of civil wars in “Chronica Comensi” and Como. The fort was part of a defensive line and it was connected with those of Sala Comacina, Lezzeno and Nessus. The other castle tower, called the Viscardi (noble family of the time) was erected down town and the tower, that was the last witness of the building, collapsed in 1876. The lower part is currently used as a dwelling.

The Parish of Holy Trinity dated from the early twentieth century and was consacrated in 1929.It is a building in neo Romanesque facade enriched by a glass canopy with figures of saints, porch, round apse and bell tower. Three kilometers from Argegno, on the road that climbs to Schignano, the Sanctuary of St. Anne, but in fact dedicated to Our Lady of Gelpio. The Sanctuary is the largest structure in the village was constructed in the seventeenth centuries, and contains stucco work from later centuries. It is believed that the construction of the church was originated by a vote by the population in time scales. Before there was a chapel dedicated to the Virgin. Following the chapel was built around the church increased in various times and finished before 1600.The Church of St. Sisinio, just outside the village on the road to San Fedele Intelvi, until the year 1632 was the matrix of the old Holy Trinity Church. It has Roman origin, rebuilt in 600 and completed in 700.The church has a historical importance as the seat of revolutionary insurrection spelled Valley Intelvi against the Austrians in 1848.It is well worth a short walk to the alley where a big mill was built around 1600 "Roggia Molinara". This canal was an ingenious system of water canals of the Cloth to provide hydraulic power to the 4 mills used to grind wheat, corn and chestnuts from the woods of Valle d'Intelvi.These factories run along the last stretch of the river are worthy curtain frame of the splendid Romanesque arched bridge, a very important structure of old Regina street (Queen Teodolinda Road).
