Grotesques are decorative figures or sculptures often found on buildings, particularly in Gothic architecture. They typically depict exaggerated human or animal forms and serve both aesthetic and functional purposes. While they are often associated with cathedrals and churches, grotesques can also be seen in secular architecture. These figures often function as water spouts, directing rainwater away from the building to prevent erosion. Grotesques can convey various themes, including mythology, folklore, or moral lessons, and they add a unique character to the structures they adorn.
