Enrico Del Debbio supervised the work from 1928, and Luigi Moretti extended the venue from 1933 to 1937. Carlo Roccatelli led the renewal project until his death in 1951, when Annibale Vitellozzi replaced him. Cesare Valle was part of the 1951 renewal. The stadium opened on May 17, 1953, as a concrete structure of 360,600 square feet (33,500 m²) clad in travertine.
Before 1990 it was almost entirely unroofed, except for the Monte Mario Grandstand. The 1988 to 1990 renovation added a Teflon and fiberglass membrane roof with a steel outer ring 95 feet (29 m) above ground, supported by 12 steel pillars. An inner steel ring is held by 88 radial cables.
Capacity is 70,634, down from 85,000 after the 1990 rebuild. It hosted the 1960 Olympic opening ceremony, the 1990 World Cup final, won 1–0 by West Germany over Argentina, and UEFA Euro 2020 matches. It stands within the Foro Italico complex.
