The main walkways are diagonal, beginning at the corners and meeting at a central oval. The plaza, which contains a large planter bed and a reflecting pool, is surrounded by a balustrade and ringed by a circular walk. Classical urns, many bearing relief figures of ancient Greeks, rest on pedestals at the entrances and elsewhere throughout the square. Ornamental lampposts contribute to an air of old-fashioned gentility. A low fence surrounds the square, and balustrades adorn the corner entrances. Oaks, maples, locusts, plane trees, and others stand within and around the enclosure, and the flowerbeds and blooming shrubs add a splash of color in season.
Rittenhouse Square is the site of annual flower markets and outdoor art exhibitions. More than any of the other squares, it also functions as a neighborhood park. Office workers eat their lunches on the benches; parents bring children to play; and many people stroll through to admire the plants, sculptures, or the fat and saucy squirrels.
