A traditional fountain is an arrangement where water issues from a source, fills a basin or jets it into the air and is drained away either to supply drinking water or for decorative or dramatic effect. In fountains sheets of water may flow over varied surfaces of stone, concrete or metal. Basins may overflow from one into another, or the overflow may imitate a natural cascade. Many fountains are located in small, artificial, ornamental ponds, basins and formal garden pools, and often they include sculpture. These wonderful architectural pieces continue to attract crowds and inspire millions around the world.
