In the main square, this small museum is a memorial to Reggio's proud role as birthplace of the Italian tricolour flag. At a meeting in the multi-tiered Sala del Tricolore in 1797, Napoleon's short-lived Cispadane Republic was proclaimed and the green, white and red tricolour was adopted for the first time. Next door in the 14th-century Palazzo del Comune is where the flag was actually conceived.
