Interesting Fact: 3,015 acres (12.20 km2) of land surrounding the observatory was donated to the City of Los Angeles by Colonel Griffith J. Griffith on December 16, 1896. In his will Griffith donated funds to build an observatory, exhibit hall, and planetarium on the donated land. Griffith’s objective was to make astronomy accessible by the public, as opposed to the prevailing idea that observatories should be located on remote mountaintops and restricted to scientists.
