Museums don’t have a monopoly on fabulous art in New York. Check out a selection of the city’s open-air sculptures and memorials during the Public Art in Lower Manhattan tour. Architectural historian Justin Ferate will guide you past commissions such as Isamu Noguchi’s Red Cube, Brian Tolle’s Irish Hunger Memorial and Tom Otterness’s The Real World, a series of whimsical figurines that dot Battery Park City.
