Construction of MGIO began in 1989. MGIO currently operates and maintains facilities for three scientific organizations. The first two telescopes, the Vatican Advanced Technology Telescope and the Heinrich Hertz Submillimeter Telescope began operations in 1993. The Large Binocular Telescope, one of the world's largest and most powerful optical telescopes, began operations using mirrors independently in 2004, with joint operations between the two mirrors beginning in 2008.
