Al 1° piano del Palazzo Comunale, mostra fotografica celebrativa dell'opera di Galileo Chini e della Volta Comunale, datata 1918, affrescata dall'artista dal titolo 'Galileo Chini a Montecatini'

It was built between 1914 and 1915, while some internal parts, such as the wedding hall, were enriched at the end of the First World War. The large and imposing structure consists of three levels, with a large front elevation, a monumental colonnaded entrance, and rich decorations on the facade, on the roof-balcony that overlooks the building, and in the interiors.
