Dolfines Guaraní, Modern skyscraper in Puerto Norte, Rosario, Argentina

Dolfines Guaraní is a pair of light grey residential towers on Avenida Estanislao López in Puerto Norte, Rosario. The shorter left tower has a curved solid cap and a facade split by a vertical seam into a narrow left section and a wider right one with stacked balconies; the taller right tower has a flat roofline, a stepped setback near the top and a grid of recessed balconies. The Spanish source gives 45 floors and 137 metres, the English source 46 floors and 136.5 metres.

The towers were completed in 2011, at which time they became the tallest structures in Argentina outside of Buenos Aires. This milestone marked an important turning point in how Rosario developed its urban landscape and approached residential construction.

The towers light up in changing colours: green for Saint Patrick's Day, light blue and white on Argentine national holidays, and green and red at Christmas. The complex stands in Puerto Norte, a former port zone redeveloped for housing from the late 2000s, part of Rosario's push to decentralise.

The location sits close to the Paraná River and offers easy access to parks, shopping, and public transportation options. Keep in mind that the buildings are primarily private residences and the towers themselves are not open to the public.

The towers' lighting changes with the calendar: green for Saint Patrick's Day, light blue and white on Argentine national holidays, and green and red at Christmas. Residents also have access to a 360° observation deck and a golf simulator.
