Gargoyles are carvings of grotesque figures, faces or creatures perching along the roofs and battlements of buildings and projecting from roof gutters. The gargoyle is one of the most recognisable characteristics of Gothic architecture.
The etymology of the word derives from the French ‘gargouille’ meaning throat. The precise purpose of gargoyles was to act as a spout to convey water from the upper part of a building or roof gutter and away from the side of walls or foundations, thereby helping to prevent water from causing damage to masonry and mortar. The gargoyle would have a trough carved into its back down which rainwater would run and exit through the characteristically large open mouth.
While common parlance uses the term ‘gargoyle’ to mean any fantastical or mythical figure used for ornamental purposes, the strict architectural usage only applies to those serving a waterspout function. Purely decorative varieties are known as grotesques, chimera or boss. See Grotesque for more information.
However, gargoyles are most commonly associated with the Gothic and Medieval architecture from the Middle Ages. Whilst gargoyles were included in the construction of many medieval buildings, such as fortresses and castles, they were most prevalent on churches and cathedrals; famous examples including those of Notre Dame de Paris [see top image].
Some of the features that would typically be depicted by gargoyles include:
- Ugly human faces.
- Mythical and imaginary creatures.
- Anthropomorphised creatures.
- Chimeras (those combining several animals).
In addition to the practical function of projecting water away from a building, gargoyles were also intended to symbolise ‘guardianship’ of the building and to ward off evil spirits. Their open mouths were symbolic of them devouring giants.
From the early-18th century onwards, buildings began to move away from ornamented and unornamented waterspouts in favour of rainwater downpipes. In 1724, the London Building Act made the use of downpipes a compulsory feature on all new construction, and subsequently the inclusion of gargoyles in architecture fell into decline. However, in an ornamental form they were revived by the Art Deco period in the early-20th century, most notably on the Chrysler Building in New York.
