If walk along the lakeside, you will come to the Church of Santissima Trinità, which dates back to 1632. Under the rose window, the facade shows a mosaic depicting the four Evangelists, Sant’Abbondio (the patron saint of Como), and Sant’Anna (patron saint of Argegno).
The pointed arch testifies the Roman origin of the town’s suburb. To confirm this origin, there are also some tombstones whose inscriptions refer to the console Max Publius Caesius Archigenes, from which the name “Argegno” seems to derive.
