The Boselli Palace was originally a fortified building of the medieval age, built in a strategic position between the rivers Brembo and Enna.
At the end of the 16th century, it was considered a junction point for the passage of the roads accessing the Upper Brembo Valley: The Mercatorum and Priula. Some of its owners were representatives of the local family Boselli, whose name was given to the palace. Before the construction of Strada Priula, travellers passing along the Via Mercatorum were obliged to pass through the inside courtyard of the palace to climb up again the Upper Valley, so the transit could be controlled by the Boselli.
The exterior of the building presents some of the interesting decorative elements, such as mask on the north facade and two dressed characters according to the medieval costume.
