Major astronomical observatories on Earth
Take a tour around the world and zoom in on modern and historical observatories. For those interested in archaeoastronomy, there are also placemarks for ancient observatories. Please contact me for any improvement on the coordinates. I would also be very happy to add any missing observatory! http://www.eso.org/~ndelmott/
