The current Montecatini Terme railway station was designed in the 1930s, replacing the now inadequate 19th-century infrastructure, mainly to accommodate the ever-increasing tourist traffic to the spa town. The design of the new complex, by FS architect-engineer Angiolo Mazzoni, is a true example of a rational railway layout, thanks to the dynamic lines of the atrium, the rounded canopies of the platforms, and, most notably, the three waiting rooms.
The three rooms, distinguished by travel class, are characterized by sophisticated design elements: from the red leather seating, mosaic-tiled walls, and curved glass panels in the first-class room, to the green leather seating in the second-class room, and the distinctive curved oak boiserie wall in the third-class room. The entire station is a true example of modern architecture and can be considered one of Mazzoni's masterpieces in railway design.
