The 13.5 km road which runs from Port de Pollença to Cap de Formentor was built by the Italian engineer Antonio Paretti. His masterpiece on Majorca, however, was the snake to Sa Calobra. Instead of being overwhelmed by what stood in his way on the cliffs, Parretti observed the Tramuntana winds and understood: where the slope was too steep, he made a curve. When he had to remove part of the cliffs, he placed the waste in other places where it was needed. The result was the two roads, which are nestled together in the mountains like abandoned silk ribbons.
