From Celts to Visconti, passing by Queen Teodolinda and Barbarossa. Here you are in Trezzo: history, culture and an impressive hydropower plant.
Trezzo, on the Adda River, is a concentrate of nature, history and culture.
Founded by Celts tribes in the fourth century BC, Trezzo saw the domination of the Roman Empire, followed by the Longobards, who transformed the town into a fortified village, thanks to the will of Queen Teodolinda who built a fortress with a central tower. In the following centuries some more stable fortresses were built around the tower: the same Frederick Barbarossa enlarged and chose it as its imperial residence.
Later Trezzo became property of the Visconti family, who even left a more impressive castle, whose ruins are visible also nowadays . rezzo’s rebirth is due to the cotton entrepreneur Crespi, owner of the homonymous cotton mill in Crespi d’Adda: he bought the entire promontory and built the majestic hydroelectric plant Taccani on the Adda river’s shore, just in front of Trezzo’s castle which is open to public as a beautiful green park.
