Perched atop Mount Graham at over 10,000 feet elevation, the Vatican Advanced Technology Telescope (VATT) is one of the world’s most fascinating intersections of faith and science. Operated by the Vatican Observatory and the University of Arizona, the VATT is part of the Mount Graham International Observatory complex. Built in the 1990s, it was among the first telescopes to use adaptive optics and a spin-cast mirror, revolutionizing modern astronomy. Though access is limited to seasonal tours arranged via Discovery Park Campus, the VATT is a unique scientific landmark — both spiritually symbolic and technologically advanced.
