Category:Articles with unknown geocoordinates

This category is populated by Coord unknown. It should contain articles which satisfy all of the following three criteria:
 * The subject is non-fictional.
 * It is associated with a fixed location on Earth.
 * The article lacks geographic coordinates (that is, latitude and longitude, such as might be coded using coord).

and one or more of the following criteria:
 * a reliable source says the subject's location is unknown AND no reliable source has been found which gives a definite location for it, or
 * reliable sources provide two or more contradictory locations.

If the location is known (but the article lacks geographic coordinates), please use Coord missing instead.
