Overview
Wednesday–Sunday
12–3 pm and 3:30–6 pm
Admission is free.
The Broken Kilometer (1979), located at 393 West Broadway in New York City, is composed of 500 highly polished, round, solid brass rods, each measuring two meters in length and five centimeters (two inches) in diameter. The 500 rods are placed in five parallel rows of 100 rods each. The sculpture weighs 18 3/4 tons and would measure 3,280 feet if all the elements were laid end-to-end. Each rod is placed such that the spaces between the rods increase by 5mm with each consecutive space, from front to back; the first two rods of each row are placed 80mm apart, the last two rods are placed 580 mm apart. Stadium lights illuminate the work’s full area of 45 by 125 feet.
This work is the companion piece to De Maria's 1977 Vertical Earth Kilometer at Kassel, Germany. In that permanently installed earth sculpture, a brass rod of the same diameter, total weight and total length has been inserted 1,000 meters into the ground.
The Broken Kilometer has been on long-term view to the public since 1979. This work was commissioned and is maintained by Dia Art Foundation.
The Broken Kilometer is closed on Independence Day, Thanksgiving Day, Christmas Eve, Christmas Day, December 31, and January 1.

Dia Art Foundation maintains 12 locations and sites across the United States and Germany, four of which are long-term installations by Walter De Maria. The American artist began to create work outside the traditional gallery space in the late 1960s, presenting his Mile Long Drawing in 1968 in California’s Mojave Desert. Beginning in the mid-1970s, Dia Art Foundation commissioned some of the artist’s most significant site-specific works, including The Lightning Field (1977) in western New Mexico, and The New York Earth Room (1977) and The Broken Kilometer (1979) in New York. Dia continues to maintain these works as well as De Maria’s The Vertical Earth Kilometer (1977) in Kassel, Germany, which is the companion piece to The Broken Kilometer.
Dia is pleased to share this film highlighting the work of Walter De Maria in celebration of our 50th anniversary.
