Aldershot observatory is a circular red-brick building with a domed roof standing on Queens Avenue in Aldershot Military Town near Aldershot, England, home to the British Army since circa 1854. Inside is an 8-inch (203 mm) refracting telescope on a German-type equatorial mount with a clockwork drive which will run for about 2 hours without rewinding, this has a facility to vary the drive rate. The telescope and observatory building were a gift from aviation pioneer Patrick Young Alexander to the British Army, a fact which is recorded by a plaque near the observatory door.
