In Italy, an arengario (also spelled arrengario or arengo; pl.
: arengari, arrengari, arenghi) is a government building in various historic periods.
[1] The word comes from the verb "arringare" ("to address"), as arengari usually have balconies from which the authorities would address the population in public speeches.
[2] It was originally the town hall of Italian medieval communes, especially in Northern Italy.
[3] As a consequence, a number of both medieval and modern (Fascist) buildings in different Italian cities are known as "Arengario".
