This is MARK DI SUVERO's sculpture called JOIE DE VIVRE, installed in Lower Manhattan's Zuccotti Park (formerly Liberty Park), a three-quarter-acre park that borders Liberty and Cedar Streets in Lower Manhattan, half a block from the World Trade Center site. The red steel structure is about 70 feet high. It is a series of tetrahedrons that are open at the ends. The soaring structure echoes the tall buildings around it. Across the street is Isamu Noguchi's famous red cube.
