The Italian national flag was born in Reggio Emilia on 7 January 1797. That day the representatives of the four cities of Reggio Emilia, Modena, Bologna and Ferrara proclaimed the green, white and red tricolor as the banner of the Cispadane Republic. The historic session took place inside the Palazzo Comunale in the large room built between 1772 and 1787 based on a design by Lodovico Bolognini to house the general archive of the Estense Duchy. The hall was later called the Congress Hall and then the Tricolore Hall and is now the seat of the City Council . The Tricolore Museum opened in 2004 to document the historical and political context in which the flag was created. A second section referring to the Risorgimento was added to the first section dedicated to the Napoleonic era in 2006. In 2017, on the occasion of a general review of the routes and the definition of a new entrance, a section dedicated to the contemporary was inaugurated which welcomed new laboratory spaces and the important nucleus of works of the Ninety artists for a flag project, an exhibition-workshop in which the theme of the flag opens up to comparison with the contemporaneity and creativity of inspiration.
