Description:
Historically, observatories were as simple as containing a sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Modern astronomical observatories typically contain one or more permanently mounted telescopes contained in buildings with a rotating or removable dome.
