Edifici Gas Natural

The Gas Natural Building, also known as the Mare Nostrum Tower, is a striking office building in the La Barceloneta neighborhood of Barcelona. Architects Enric Miralles and Benedetta Tagliabue designed the high-tech-style tower, which was completed in 2005 and opened in 2008. With twenty floors and a height of 86 meters, it shapes the skyline near the coast. Particularly eye-catching are two horizontal glass blocks that jut out at sharp angles from the main tower. The building served as the headquarters of the energy company Naturgy until 2019, when the company moved its head office to Madrid. Today the tower is owned by the real estate company Inmobiliaria Colonial and stands southwest of the well-known skyscrapers Hotel Arts and Torre Mapfre.
