This is the highest hotel in the Swiss Alps, located 3,100 meters (10,170 feet) above sea level (this is where it gets its name from). It took ten years to build the 3100 Kulmhotel Gornergrat, and it was completed in 1907.
Two observatories were constructed in 1996, one on each of the tall towers. They allow astronomers to take advantage of the clear air and conditions and observe the galaxies in exceptional detail.
The observatories are so technologically advanced that students and professors from the University of Cologne go there to study.
