Wikipedia defines an observatory as "a location used for observing terrestrial, marine, or celestial events," and its location is often chosen specifically to improve what it can observe. Browsing this way collects every observatory built in the same place or type of place.FactsLocationSourcesComments (0)Reader Challenges (0)FactsComparisonField Origin EraWell-attested1932 1LocationFilter Results14 entriesArea (sq km)All41,865 (1)242,500 (1)357,022 (1)377,975 (1)632,702.3 (1)756,102 (1)1,220,813 (1)3,287,263 (1)7,688,287 (2)9,572,900 (1)9,866,632 (1)9,984,670 (1)14,200,000 (1)Country CountAll1 (1)30 (1)Highest Elevation (m)All2228 (1)4892 (1)Independence or Founding YearAll1776 (1)1801 (1)1818 (1)1867 (1)1901 (1)1910 (1)1947 (1)1949 (1)PopulationAll0 (1)18,130,208 (1)19,629,588 (1)27,801,023 (2)41,417,056 (1)63,419,000 (1)69,081,996 (1)69,414,000 (1)83,497,147 (1)122,587,000 (1)340,587,000 (1)1,210,854,977 (1)1,407,698,000 (1)Show ResultsBrowseCompareSelect all 14AntarcticaLocation1 entryAustraliaLocation3 entriesAustraliaLocation1 entryCanadaLocation3 entriesChileLocation2 entriesChinaLocation1 entryFranceLocation2 entriesGermanyLocation1 entryIndiaLocation1 entryJapanLocation1 entryNetherlandsLocation2 entriesSouth AfricaLocation3 entriesUnited KingdomLocation2 entriesUnited StatesLocation5 entriesSources1.
