Zero Milestone, Washington DC

The Zero Milestone is a zero mile marker monument in Washington, D.C. intended as the initial milestone from which all road distances in the United States should be reckoned when it was built. At present, only roads in the Washington, D.C. area have distances measured from it.LocationThe monument stands just south of the White House at the north edge of the Ellipse, within President's Park. Atop the monument is a bronze 16-point compass rose with a very small worn-down pyramid at its center whose top serves as a National Geodetic Survey benchmark (HV1847). Coordinates: (NAD83) Altitude: 8.382 m (27.50 ft) (NAVD88)DescriptionDesigned by Washington architect Horace W. Peaslee, the monolith is about 2 feet square and about 4 feet high. It is made of precambrian Milford granite from Milford, Massachusetts, light pinkish to greenish gray, with spots of black biotite mica. The bronze disk on top of the milestone is "an adaptation from ancient portolan charts of the so-called wind roses or compass roses from the points of which extended radial lines to all parts of the then known world—the prototype of the modern mariner's compass."

  • Geography nuts who collect places of geographic importance must visit the site. Right in front of the Whitehouse, surrounded by any number of tourists who couldn’t care less, but a great stop.  more »
  • The index which is the origin calculation of the road in the United States which corresponds to the road origin of Nihonbashi in Japan. I went to check the map in advance because it was listed in the guidebook, there is a simple enough to tend to pass without noticing it.
