Piz Vatgira, or more precisely a lower 2,981 metre-high summit 350 metres south of the main summit, lies exactly above the Gotthard Base Tunnel, at its deepest point. The tunnel, the longest and deepest in the world, runs below the ground. Piz Vatgira is the highest of the three main peaks above the base tunnel, the other two being the Chrüzlistock and Pizzo dell'Uomo.
