A Gargoyle by definition is a grotesque carved human or animal face or figure projecting from the gutter of a building, typically acting as a spout to carry water clear of a wall. When not constructed as a waterspout and only serving an ornamental or artistic function, the correct term for such a sculpture is a grotesque, chimera, or boss. However, in common usage, the word "gargoyle" is generally used to describe any monstrous sculpture, whether intended as a waterspout or not (Wikipedia).

Many medieval cathedrals have gargoyles - the most famous of these are at Notre Dame de Paris.  The photos below were taken by Jess Nicol when she made the Gargoyle Pilgrimage in December 2017.
