Carnival Liberty is a Conquest-class cruise ship operated by Carnival Cruise Line. Built by Fincantieri at its Monfalcone shipyard in Friuli-Venezia Giulia, northern Italy, she was christened by actress Mira Sorvino in Civitavecchia, Italy, on July 19, 2005. Carnival Liberty was the first ship to feature Carnival's Seaside Theater—a 12-foot (3.7 m) high by 22-foot (6.7 m) wide LED screen. Located by the midship pool on the Lido deck, it is used to show movies, sporting events, concerts and other ship programming.
