The Audubon Park Historic District is not just an architecturally significant group of buildings frozen in time, but also a vibrant community with opportunities for residents to participate in neighborhood activities, particularly through the Riverside Oval Association (ROA). Among other activities, ROA volunteers care for the “oval,” a distinctive landmark at the intersection of Riverside Drive and 156th Street. Officially named the Charles and Murray Gordon Memorial Park, the “oval” is the centerpiece of the Audubon Park Historic District, a reminder of the elms, oaks, and pines that once covered the hillside above Audubon’s house and a source of changing colors and textures year-round.
