The Civic Museum of Erba is situated in the Villa Ceriani-Bressi;built in the late 700s by an architect named Gianluca Gavazzi della Somaglia upon a pre-existing 5th century building of which lowered archways remain in some rooms.
The museum arose in 1961 by will of the teacher Fernanda Isacchi so that it would constitute an intermediate reality between the main museums of Como and Lecco and considering the geographical location of Erba;at the border of the Valassina and the beginning of the hilly Brianza;it stands out as the museum of high Brianza territory and of the "Larian Triangle".The museum was completely renovated in 1999;creating a path that goes backwards in time from the modern times to the geological ages.The main stages of the local history and prehistory and of the "Larian Triangle" are documented in the eight rooms of the museum.The outfit of Canzo tombs (Copper Age and Bronze Age);a lombardian sword with silver damascening decorated handle and a map from Teresian times are the main and most precious finds.In the courtyard there are two "massi-avello" (tombs excavated in erratic rock;dating back to the IV century and the VI century AC;spread in the "Larian Triangle" and the Canton Ticino) and some sarcophagus with relative roofs upon.
