a central feature of meridian hill park is the 13-basin "cascading waterfall" in the lower-level formal garden. the fountains are designed with a recirculating water system which, through an elaborate series of pumps, supplies water to two large circular fountains on the upper level, and cascade found on the lower. the many walls and stairways of the site's composition add variety to the park, and because the central structure is on a hillside, some of the stairways are rather dramatic. the park also contains well-designed textured-concrete benches and urns, and patterned-concrete walkways.
