The courtyard at Rozzol Melara measures two hundred meters on each side, which makes it larger than any square in Trieste. Two L-shaped blocks of exposed concrete enclose it, one of them twice the height of the other, climbing from seven to fifteen stories as the ridge falls away toward the gulf four kilometers below. Concrete pylons spaced every fifteen meters carry the blocks down to a slope they never quite touch, opening porticoes deep enough to walk through, and above them the facades resolve into loggias at the scale of a single room. Seen from the coastal road, none of that is legible; one can only see a gray line drawn across the hills.
Inside the enclosure, the Istituto Autonomo Case Popolari of Trieste built the rest of a city. The 648 apartments account for less of the plan than the schools, the post office, the health center, the parish hall, the twenty-odd shops and the two-level garage, all reached through covered streets that run the length of the blocks and cross the court in a raised walkway, so that the route from a front door to a grocery or a classroom passes through collective space without ever going outdoors. Twenty-nine architects worked on it under the coordination of Carlo Celli, drawing on sociological studies commissioned before the project.
