A wide, open Romanesque loggia from the 13th century, built as a meeting place for the noble class to play chess, talk, and watch tournaments in the street outside. It is one of the only surviving structures of its kind in northern Italy — most cities walled off their public meeting spaces long ago.
Faded frescoes of knights and battle scenes are still visible on the inner walls under the wooden roof beams. The loggia is open to the air on three sides and now sits on a small piazza used for outdoor concerts in summer.
