There are places where not only heaven and earth meet, but also two worlds. One such special place is located just above Oberlech at 1,780 meters above sea level. There, at Tannegg, surrounded by impressive alpine scenery and the natural beauty of the Arlberg, the Skyspace-Lech by American artist James Turrell is an underground color-light space that could not be more artificial and otherworldly, combining the experience of art and nature.
