A striking appearance of a human Face on Mars in
a photo taken by Viking 1 in 1976. Whilst generally believed to be an optical illusion (pareidolia), others view it as evidence of a long-lost Martian civilization. Other features are argued to have been observed, such as apparent pyramids. A popular belief is that these are part of a ruined city.
