Stadio Giuseppe Sinigaglia

Como had no stadium of its own, and it was decided to build one for the Volta celebrations of 1927, held in honour of Alessandro Volta, a native of the city. Work began in October 1926 on the ground of the existing Campo polisportivo Garibaldi, given over by the podestà Carlo Baragiola. The stadium was built on the orders of Benito Mussolini to the design of the Milanese architect Giovanni Greppi, and its construction was one of the first examples of rationalist architecture in Italy. It was equipped with two tracks, a velodrome of 500 metres and an athletics track of 450 metres, which ran around a football pitch of about 7,200 square metres; the stands held 6,000 people. Lando Ferretti, president of CONI, visited in July 1927 and came away enthusiastic, and the ground was inaugurated on 30 July 1927.

It was dedicated to Giuseppe Sinigaglia (1884-1916), a war volunteer decorated for valour who died on Mount San Michele. Sinigaglia had been a world rowing champion, and had also wrestled, run, jumped and thrown the discus at the Campo Garibaldi over which his stadium was built. In that first year the ground held the first track cycling "olympics", gymnastics "olympics" and international football matches. Through September it staged large firework displays, and four cash prizes were awarded with a diploma from the Volta Executive Committee: 18,000 lire for the first, 12,000 for the second, 10,000 for the third and 8,000 for the fourth.

In 1932 the Opera Nazionale Balilla took control of the ground as its regional headquarters and commissioned Gianni Mantero to add a swimming pool, a gymnasium, a fencing room and offices. As part of the arrangement the original neo-classical façade was replaced with something closer to the vogue for rationalist architecture.

From 1960 to 1974 the classic cycling race Giro di Lombardia finished inside the stadium, and in 1977 the ground hosted the first of three matches played there by the Italy national under-21 side. Beginning in 1975 a run of interventions partially undid the stadium's original character: the athletics and cycling tracks were taken out, the central grandstand was rebuilt and the distinti stands were extended to the edge of the playing field once metal bleachers had been laid, and in the course of that work the opening in the middle of the bleachers, which had allowed a view of the lake from the covered grandstand, was closed up. The lakeshore setting remains the ground's distinguishing feature, visible from most of the stands, and for it the sports journalist Gianni Brera called the Sinigaglia "the most beautiful in the world". In 1990 the Tribuna stand was demolished and rebuilt.

The west curve, known as the Curva Azzurra or Curva Como and the home of the club's organised support, was completely rebuilt in 2002 as two staggered metal bleachers forming a wedge that juts outwards from the ground, holding around 5,000. Further stands were added to the east curve, part of it given over to visiting supporters and its masonry section rebuilt, so that Como could play the 2002–03 Serie A season in a stadium with a capacity of 13,900. The club's fortunes then fell away through bankruptcies and restarts from the amateur leagues, and the official capacity was cut hard, to fewer than 5,000 seats, once the oldest part of the distinti and the home section of the east curve had been shut. Minor interventions followed to keep the ground to the standards demanded of it: in 2015–16 Como had to play its first home matches in Novara while summer work went on, which brought in turnstiles at the entrances, external pre-filtering zones and security cameras, and in the summer of 2017 the roof of the Tribuna, still the only covered sector, was rearranged, sending Como to Seregno for the opening matches of the 2017–18 season and to Carate Brianza for a Coppa Italia Serie D tie.

The stadium has been used for more than football. Pope John Paul II's helicopter landed there on 4 May 1996 during his visit to the city. The Italy under-21 side returned in 1993 and 2002. The English hard rock band Deep Purple played there on 13 July 2004 and the singer Jovanotti on 7 July 2008. Between 29 March and 1 April 2013 the ground held the semi-finals and finals of the NextGen Series.

In 2008 an investigation by the Rai News 24 journalist Angelo Saso raised the possibility of a link between cases of amyotrophic lateral sclerosis among six former Como players, Celestino Meroni, Piergiorgio Corno, Albano Canazza, Adriano Lombardi, Stefano Borgonovo and Maurizio Gabbana, and the herbicides, poisons and paints used on the pitch in the 1970s and 1980s, together with the possible presence of waste in the subsoil: residues of coal combustion, fine residues from locomotives, slag from electrical industries, cadmium, calcium silicates, chromium, nickel, manganese and lead, drainage material from the foundries at Dongo. That same year the magistrate Raffaele Guariniello, advised by Professor Adriano Chiò, opened an inquiry into all of it. The comune of Como, through Fulvio Caradonna, then its councillor for major works, declared the suspicions unfounded.

Como's return to Serie B brought work in the summer of 2021: seats were installed in every sector open to the public, the turf was relaid, the benches were sunk into the ground and VAR and goal-line technology were put in. In the summer of 2023 the lighting was modernised throughout, along with the four light towers that had caused blackouts in previous seasons and had interfered with flight operations at the neighbouring seaplane base. Two of those towers, the pair flanking the west curve, are painted white and red for the same reason, and a wind sleeve stands beside one of them. When the club went up to Serie A again in 2024 the whole distinti sector, unfit for use since 2016, was rebuilt and fitted with seats, bringing the ground to 10,584 places. In February 2025 the away supporters' sector was enlarged by 175 seats through the reopening of the parterre.

The stadium belongs to the comune of Como, which grants it to the football club for its home matches, and it carries Italian national heritage designation. In February 2025 the club's ownership put a redevelopment scheme to the mayor of Como, proposing to take the seating to 15,000 and to rework the area around the ground, with completion expected by 2028. A further phase of modernisation began on 18 May 2026, required if the club were to take part in UEFA competitions: the Curva Como was demolished and rebuilt in reinforced concrete to meet UEFA requirements, taking capacity to 12,379 seats, and the work also covered an enlarged pitch, new undersoil heating, upgraded media and hospitality areas and better accessibility.
