The Sphere, Memorial sculpture in Financial District, New York City
The Sphere is a cast bronze sculpture by Fritz Koenig, 7.6 meters tall and 5.2 meters in diameter, assembled from 67 bronze segments. Its upper half forms a segmented globe with dark seams and a central hole, while the lower half is split open by jagged black panels and torn edges. The sphere rests tilted on a crumpled, splayed base set on gray stones.
The work stood at the center of the original World Trade Center complex starting in 1971 and survived the September 11, 2001 attacks heavily damaged. It was moved to Battery Park in 2002, then returned to the rebuilt area in 2017.
Visitors often refer to the work simply as "the Sphere," a name that recalls its earlier role as a fountain centerpiece in the center of world trade. The surface still carries marks from the 2001 attacks, visible signs that have become part of the city's remembrance culture.
The monument stands in Liberty Park, which is open year-round and accessible from all sides. The small park on a raised level also offers a wide view over the adjacent memorial grounds.
Originally designed as a rotating fountain, the object completed a full turn every 15 minutes. Weighing around 20,000 kilograms (45,000 pounds), the installation was one of the largest moving sculptures of its time.
