Monte Mario (English: Mount Mario or Mount Marius) is the hill that rises in the north-west area of Rome (Italy), on the right bank of the Tiber, crossed by the Via Trionfale. It occupies part of Balduina, of the territory of Municipio Roma I (Roma Centro), of Municipio Roma XIV (Roma Monte Mario) and a small portion of Municipio Roma XV of Rome, thus including part of the Quarters Trionfale, Della Vittoria and Primavalle. The same toponym also identifies the urban area which extends over the hill, close to Via Trionfale and the first stretch of Via di Torrevecchia, with the railway station of the same name. It is the highest (139 m) hill in the town and, together with the Janiculum and the Pincius, one of the most scenic spots in the city, especially in the place called "Zodiac", which offers a south and west view of the main architectural monuments of the city, of the Vatican City, of the Alban Hills, of the Monti Tiburtini, of the Monti Prenestini and of the highest peaks of western central Apennines. Here, moreover, begins the longest Linear Park in Rome, which connects the town to the Parco di Monte Ciocci. The location has been chosen as trigonometrical station in the Gauss–Boaga cartographic projection, giving rise to the datum Roma 40. Although it is the highest hill in the modern city of Rome, Monte Mario is not one of the proverbial Seven Hills of Rome, being outside the boundaries of the ancient city.

The Gauss–Boaga projection is a map projection used in Italy that uses a Hayford ellipsoid.

Foro Italico is a sports complex in Rome, Italy, on the slopes of Monte Mario. It was built between 1928 and 1938 as the Foro Mussolini (literally Mussolini's Forum) under the design of Enrico Del Debbio and, later, Luigi Moretti. Inspired by the Roman forums of the imperial age, its design is lauded as a preeminent example of Italian fascist architecture instituted by Mussolini. The purpose of the prestigious project was to get the Olympic Games of 1940 to be organised by fascist Italy and held in Rome.

The Stadio Olimpico del Nuoto (Olympic Swimming Stadium) is an aquatics centre at the Foro Italico in Rome, Italy. Inaugurated in 1959, it was designed by the architects Enrico Del Debbio and Aniballe Vitellozzi to host the swimming, diving, water polo, and swimming portion of the modern pentathlon events for the 1960 Summer Olympics. The venue was refurbished to host the 1983 European Aquatics Championships, and reconfigured and expanded for the 1994 World Aquatics Championships. The stadium was the main venue of the World Championships again in 2009, and will host the European Aquatics Championships in 2022.

It is a vocational university, the only Italian state university dedicated to sports and movement sciences. It was created in 1998 when it replaced Rome's Istituto Superiore di Educazione Fisica (ISEF) whose activity had been centred on higher education for P.E. teachers.

The Foro Italico is the greatest Italian sports complex, including indoor and outdoor swimming-pools, gyms of many dimensions, tennis courts, two track-and-fields arenas and the big Olympic Stadium.

The Stadio Olimpico (English: Olympic Stadium) is the largest sports facility in Rome, Italy, seating over 70,000 spectators. It is located within the Foro Italico sports complex, north of the city. The structure is owned by the Italian National Olympic Committee and it is used primarily for association football. The Stadio Olimpico is the home stadium of the Roma and Lazio football clubs, and also hosts the Coppa Italia final. The Italian Rugby Union team also use the stadium for their home matches. It was rebuilt for the 1990 FIFA World Cup and it hosted the tournament final. Despite being an Olympic stadium, therefore ostensibly dedicated exclusively to sport, musical concerts are also held, in particular the concert by Claudio Baglioni on 6 June 1998, which still holds the record attendance at the Olimpico with a total of over 100,000 spectators, thanks to the fact that the stage was located in the center of the stadium and the public surrounded it filling all the seats.Rated an UEFA category four stadium, it has also hosted four European Cup/Champions League finals, the most recent being the 2009 UEFA Champions League Final. Outside football, the stadium is used by the Italian national rugby union team and it is Italy's national athletics stadium. Occasionally, it hosts concerts and events.

The Stadio dei Marmi ("Stadium of the Marbles") is one of four stadiums in the colossal sports complex the Foro Italico, initially named Foro Mussolini. The other stadiums are the Stadio Olimpico, the Stadio del tennis Romano, and the Stadio Olimpico del Nuoto. It was designed in the 1920s as a complement to the annexed Fascist Academy of Physical Education (now the seat of CONI, Italian Olympic Committee), to be used by its students for training. The Stadio dei Marmi first opened in 1932, on the 10th anniversary of the March on Rome, near the Roman neighborhood Monte Mario, by the architect Enrico Del Debbio under the Fascist ruler Benito Mussolini. The Stadio dei Marmi is encircled by sixty, 4-meter tall classical statues of athletes made from Carrara marble. The stadium was built to celebrate Fascist accomplishments and the Gioventú del Littorio, the youth movement of the National Fascist Party of Italy. In its twenty-year reign, the Fascist regime used sports to introduce and instill new fascist traditions, ideals, customs, and values, with the goal of forming citizen warriors. The Stadio dei Marmi was used to host some of the field hockey preliminaries for the 1960 Summer Olympics and also hosted the opening ceremony for the 2009 World Aquatics Championships.
