The Giant Meterwave Radio Telescope (GMRT) is a group of 30 radio telescopes, each 45 meters across, built in 1995 near Pune, India. The individual telescopes coordinate to act as a giant telescope 25 km wide. If wind-speeds rise above 60 kph, the dishes all face directly upright and lock into place to protect the machinery from buckling. When technicians go to check on the individual telescopes they bang on the doors before entering. This is to scare away any snakes, which are common in the arid lands the array was built on.
