Founded in 1946 as Rondinella Firenze in a restaurant in the district of San Frediano (in Florence) and from the very beginning it has won the title of the Florentine "first alternative" to the more famous and glamorous Fiorentina or la Viola as they are known in the Tuscan capital.

In 1953 the municipal administration assigned the Torrino di Santa Rosa as its registered office to Rondinella, a medieval stone building on the banks of the Arno, almost a monument to Florence.

1957 brought about a further promotion into Serie D which saw them face some of the best known Tuscan teams for the first time, such as Empoli, Pisa and U.S. Pistoiese.

In 1979, Rondinella Marzocco Firenze finally established a permanent residence, moving into the Stadio Comunale delle Due Strade, where they continued to play to this day.

On the walls of the bar in which the club was formed, as a probable residue of a carnival party, some paper swallows were still glued; thus the idea of adopting the name Rondinella was born.
