Palazzo Terragni, the former Casa del Fascio in Como, is one of the most famous Italian rationalist buildings. A landmark building in modern European architecture, it was designed by Giuseppe Terragni in 1932. A masterpiece of lightness thanks to the symmetrical effect of solids and voids, of glass and reinforced concrete pillars and the innovative use of alloys and Bottoncino marble. A clean and airy construction, a pure white and compact prism whose rectangular openings lighten and illuminate the entire piece of architecture. The building dialogues wonderfully with the other entities close by: Brunate mountain, the Teatro Sociale, Como’s Duomo. It is shaped like a large parallelepiped formed by surfaces of pure geometrics: on one side of 33.2 metres, half as short in height, there are solids and voids that create a simple but effective pattern of evocative chiaroscuro and transparent details. The materials are arranged in forms that create parallel and perpendicular lines, ensuring the harmony of the entire piece of architecture. The hall is covered by glass brick curtains, between which there is a long sheet of glass that offers a glimpse of the hill above.
