Torre Aqualina, Residential skyscraper in central Rosario, Argentina.

Torre Aqualina is a residential skyscraper in central Rosario with 40 floors of glass and concrete rising 125 meters high. The building contains luxury apartments and offers views across the Paraná River toward downtown.

Torre Aqualina was designed by Buenos Aires-born architect Mario Roberto Álvarez and developed by the Rosario firm OP Developers, with the construction contract awarded to Constructora Sudamericana. The project was presented in 2003, the facade work began in December 2007, and the tower topped out on 19 May 2008, opening in 2009. Two judicial rulings sought to halt the works pending an environmental study, but in May 2007 the Supreme Court of Justice of Santa Fe Province ruled such a study unnecessary.

The tower's name, Aqualina, and its 40 apartments with views over the Paraná River made it a reference point for vertical living in Barrio Martín, a few blocks from the National Flag Memorial. Neighbours contested the project from its 2003 presentation, arguing it would harm the landscape and ecology, while the developers insisted it would harmonise with its surroundings.

The tower sits at the corner of San Luis and Alem Streets in the city center, making it easy to reach on foot. Underground levels provide parking, and the location puts you near shops and dining options.

The tower was the first building in Rosario tested aerodynamically in a wind tunnel, by CPP of Denver, using a scale model and its surroundings within a 600 m radius. The test found resistance to wind pressure averaging 400 kg per m², and the foundation reached 35 m deep.
