The Old Town Hall probably dates back to as early as the 14th century. It was destined to host the assemblies of the city representatives and then the Town Hall, before the new one was built. Its present-day aspect is an example of 18th century Piedmontese-Baroque. Above the entrance door, an inscription in memory of the visit by Emperor Charles V and above that, Cagliari's coat of arms. It then became the city's conservatoire and it's now a cultural space used by the city council to host exhibitions.
