Gargoyle (Paperback)

High Quality Content by WIKIPEDIA articles! In architecture, a gargoyle is a carved stone grotesque with a spout designed to convey water from a roof and away from the side of a building. Preventing rainwater from running down masonry walls is important because running water erodes the mortar between the stone blocks. Architects often used multiple gargoyles on buildings to divide the flow of rainwater off the roof to minimize the potential damage from a rainstorm.
