The Altis, as the sanctuary as was originally known, was an irregular quadrangular area more than 200 yards (183 meters) on each side and walled except to the North where it was bounded by the Kronion (Mount Kronos). It consisted of a somewhat disordered arrangement of buildings, the most important of which are the Temple of Hera (or Heraion/Heraeum), the Temple of Zeus, the Pelopion and the area of the great altar of Zeus, where the largest sacrifices were made. There was still a good deal of open or wooded areas inside the sanctuary. The name Altis was derived from a corruption of the Elean word also meaning "the grove" because the area was wooded, olive and plane trees in particular.
