Cydonia_Face_on_MarsCydonia is an area of Mars that has generated a lot of interest and conspiracy theories.  When it was first photographed by NASA’s Viking orbiter in 1976.  The pictures appeared to show a number of peculiar anomalies including a series of pyramid-shaped objects on the surface and a large structure that resembled a humanoid face.

In more recent years newer NASA Mars orbiters have returned to  “Cydonia” for additional photographs of the region showing that the “face” was nothing more than a natural rock formation, however, the original pictures and the area itself are still under some considerable debate.
