Aerial view of the Virgo interferometer
The Virgo interferometer is located in the south of Pisa in Italy. The main building in which the laser beam is generated, sent into the interferometer arms, and measured on photodiodes is visible at the bottom of the images. The buildings around the two 3 kilometer long arms are visible: the laser beam propagates all the arms and is reflected by a mirror
suspended in a building at each end.
