Arcetri Astrophysical Observatory
Arcetri Astrophysical Observatory is an observatory in Florence, Italy, founded in 1872 as a memorial to Galileo, who spent his period of house arrest near the site of the observatory. It is now primarily a research institute funded by the Italian government. The instruments at the site are an old 36-cm (14-in) refractor and a solar telescope. A 1.5-m (60-in) infrared telescope is located at an altitude of 3,200 m (10,500 ft) near Zermatt.
