The origins of the Cristoforo Colombo lie in the situation of the Italian Line at the end of World War II. The war had been devastating to them, as two of their newest and largest ships - the and - had been destroyed. The Italian Line at this point decided to build only moderately-sized ships that were very luxurious, comfortable, and stylish. The Cristoforo Colombo was built in Genoa at the Ansaldo Shipyards. The Andrea Doria was already built by the time Cristoforo Colombo was completed. She was launched in 1953 and was ready for a 1954 maiden voyage. When launched, the Cristoforo Colombo was larger than the Andrea Doria. Hence, the ship was the largest merchant ship in Italian service.
Italian Line service
After the Andrea Doria was sunk after a collision with the in 1956, the Cristoforo Colombo was on her own until 1960 when the ship was joined by the Andrea Doria's replacement, SS Leonardo da Vinci. In the spring of 1964, the Cristoforo Colombo carried the Pietà from the Vatican to the 1964 New York World's Fair. Pietà was put in a crate that was filled with plastic foam, which was lowered onto a rubber base in the first class pool where the least damage was likely to happen to it. During the actual loading, the Cristoforo Colombo had been put in dry dock so that she would not move and jeopardize the crate and its content. Only easily removable snap hooks secured the crate so that it could be released easily in case of accident. In case the Cristoforo Colombo sank during the voyage, the crate had the ability to float. In New York, the crate was lifted by a heavy-lift floating crane onto a barge that was put alongside the ship. The Cristoforo Colombo and the Leonardo da Vinci were kept as the flagships and the prime Italian ships on the North Atlantic until 1965, when the new and were placed into service. She was painted entirely white in 1966 in order to match with the other ships in the Italian Line, who had abandoned black as a hull color.
In 1973, the Cristoforo Colombo gave up the New York service. It was therefore redirected to the Genoa-Barcelona-Lisbon-Rio-Montevideo-BuenosAires service to replace the that had suffered serious mechanical problems. As the South American service accepted a ship of sub-standard maintenance, she stayed, until 1977. She was then sold to Venezuela, where she was used as an accommodation ship for workers at Ciudad Guayana. In 1981, the Cristoforo Colombo was sold to US scrappers. However, upon arrival at Kaohsiung, Cristoforo Colombo was towed to Hong Kong with hopes of returning to service. As the ship was expensive to operate and was in poor condition after her time in Venezuela, the Cristoforo Colombo was towed back to Kaohsiung in the autumn of 1982 and scrapped.
