The sports club, born in 1912 during the Austro-Hungarian dominion, started its activity after the end of
World War I. The team, already active in 1919, grew progressively until entering the Seconda Divisione of the Italian football championship, the last step before the highest national category, and it witnessed its fusion in 1923 with two other local clubs: S.C. Monfalcone and G.S. Cantiere Navale Triestino. Unexpectedly winning the C round of
Prima Divisione championship in 1929, the team was admitted to the first
Serie B for
1929-1930 and for the following two seasons. In November 1932 the great financial crisis of
Cantiere Navale Triestino, the company managing the local harbour, forced the Italian team to retire after 6 days, which meant its relegation to the
previous category. Being in trouble in the period before the
Second Italo-Ethiopian War, it managed to make up the lost ground and after only 3 seasons it went back playing in third level championships, which from 1935 to not long ago were called
Serie C. After interrupting the activities for warfare, in 1945 the sports club split in two: Associazione Calcio Monfalconese (ACM) and Cantieri Riuniti dell'Adriatico Monfalcone (CRDA Monfalcone). Such division didn't last long and, after 7 years of individual activities, the two teams unite in the name of CRDA Monfalcone. In 1962 Monfalcone won
Serie D Championship and could therefore take part in
Serie C 1962-1963; in 1968 it changed name into
Associazione Calcio Monfalcone. It was relegated from
Serie C at the end of
1970-71 championship and for about 20 years the team competed for championships in
Serie D and
Eccellenza. In 1993 the club closed and, in 1994, a new sports club was founded with the name of Unione Sportiva Calcio Monfalcone. Starting from
Terza Categoria, it shortly escalated 5 categories until being promoted, in 2002, to
Serie D. At the end of the
2010–11 Eccellenza season, the club relegated to
Promozione, but decided to merge with the second team of the city, Fincantieri Calcio, in order to remain in Eccellenza and build a stronger club, taking the current name in the process. In
2012–13 Eccellenza season, after 10 years, the club was promoted back to
Serie D where it remained only for one year given that at the end of
season 2013-14 it was relegated to
Eccellenza. Winning the latter championship it was promoted back again to
Serie D, but this didn't last the next season given the economic situation of the club. Winning 2016-17 championship in
Terza Categoria, the team was promoted to
Seconda Categoria. ==Colours==
