The Vertical Earth Kilometer, Public art installation in Friedrichsplatz Park, Germany
A one-kilometer-long solid brass rod with a diameter of five centimeters extends vertically into the ground, marked by a red sandstone plate at surface level.
The installation process in 1977 required specialized drilling equipment to bore through six geological layers over a period of seventy-nine days.
The artwork represents a connection between surface and depth, with only a small circular brass top visible while the majority remains concealed underground.
Located at the intersection of footpaths in front of the Fridericianum museum, the installation consists of multiple brass sections measuring 167 meters each.
The drilling operation for this permanent installation reached a depth equivalent to the height of three Empire State Buildings stacked vertically.
