One of the most well known cases is the neighborhood of Isola. Despite its position, this area has been for a long time considered as a suburb since it has been an isolated part of the city, due to the physical barriers such as the railways and the Naviglio Martesana. In the 1950s, a new business district was built not far from this area, but Isola remained a distant and low-class area. In the 2000s vigorous efforts to make Isola as a symbolic place of the Milan of the future were carried out and, with this aim, the Porta Garibaldi-Isola districts became attractors for stylists and artists. Moreover, in the second half of the same decade, a massive urban rebranding project, known as Progetto Porta Nuova, started and the neighbourhood of Isola, despite the compliances residents have had, has been one of the regenerated areas, with the Bosco Verticale and the new Giardini di Porta Nuova.
