A reflecting pool, also called a reflection pool, is a water feature found in gardens, parks and memorial sites. It usually consists of a shallow pool of water with a reflective surface, undisturbed by fountain jets.
Design
Reflecting pools are often designed with the outer basin floor at the rim slightly deeper than the central area to suppress wave formation. They can be as small as a bird bath to as large as a major civic element. Their origins are from ancient Persian gardens.
