A number of Trieste teams had played in the first division Serie A, the most successful of which was Società Ginnastica Triestina (from the 1930s to the 1960s) that won several national championships in the 1930s and 1940s.

After many years spent between the third and fourth division, in 2010 Eugenio Dalmasson was appointed Head Coach.

Finally in 2012, the team reached the promotion to the second division with a win against Chieti in an epic game-5 in front of 6000 people.

In January, 2023, 90% of the club was acquired by San Francisco-based Cotogna Sports Group with the remaining 10% by Trieste-based Trieste Basket.
