The Broken Kilometer is a single-room installation by Walter De Maria at 393 W Broadway in New York City. Five hundred polished brass rods form a work that spans one kilometer, set in a quiet hall with natural light. The rods change as their brass oxidizes, so the installation looks different over time and in different light. It suits visitors curious about postwar art and works that invite close looking. Staff can explain the piece’s design and care. Entry is free.
Looking at the rods
The installation consists of 500 polished brass rods arranged to make a kilometer-long work. Its design and perspective are details to discuss with the gallery attendant, who can answer questions about how the piece was made and is maintained.
Changes in the brass
The rods’ appearance shifts as the brass oxidizes in New York’s environment. They are polished every two years, so a visit after polishing offers a different view from one made later in the cycle. The New York Earth Room is another Dia-supported installation to include in a visit to the area.
