Running Fence was an installation art piece by Christo and Jeanne-Claude, which was completed in California on September 10, 1976. The art installation was first conceived in 1972, but the actual project took more than four years to plan and build. After it was installed, the builders removed it 14
days later, leaving no visible trace behind.
