The patron saint of Ramacca is Saint Joseph, celebrated on 19 March; the church dedicated to him stands alongside the mother church, dedicated to the Nativity of Mary Most Holy. Ramacca's territory was detached from the municipality of Caltagirone in 1197 under Emperor Henry VI of Swabia, becoming his fief: passed from hand to hand among the Cardona, Passaneto and Modica families, it finally reached the Gravina family, one of whom became its first lord in 1490.
On 7 October 1688 King Charles II granted the title of prince to Sancio Gravina, lord of the fief, on condition that he build a settlement there and provide land for cultivation: it was only in 1693, however, that his son Ottavio Gravina began to populate Ramacca, granting houses, land and territorial immunity to persecuted and politically condemned people of the Kingdom of the Two Sicilies. The population, which at that time numbered about 400 inhabitants, rose to 1,560 by 1820, the year feudalism was abolished, when Ramacca was designated the seat of a magistrate's court.
