Monument 258

As we work toward a truly binational park, the Friends of Friendship Park propose the restoration of unrestricted public access to three locations: the Binational Friendship Garden, the beach below Monument Mesa, and the historic Monument 258. As can be seen from the 1976 photo taken from the international boundary looking east (top photo), Monument 258 stands as the physical and symbolic centerpiece of what was clearly designed to be an open, binational plaza.

History:  The historic monument standing at the center of Friendship Park, marks the origination point of the new international boundary as negotiated by the United States and Mexico in the Treaty of Guadalupe-Hidalgo at the end of the U.S.-Mexico War. The original monument was put in place by the U.S.-Mexico Boundary Commission in 1849. In 1894 a new survey team, chartered by the International Boundary Commission placed a refurbished monument – now called “Monument 258,” because this commission had worked from east to west – atop Monument. In Mexico, the monument has been known as "La Mojonera." Until recently there were little more than symbolic markers of the international boundary at this location: low hanging ropes, barbed wire, or nothing at all.


Current Design and Access:  As can be seen in the 2013 photo taken from the international boundary looking west (bottom photo), the security wall erected by the Department of Homeland Security from 2009-2011 encircles the monument several feet to its northern side, rendering it entirely inaccessible, and in fact barely visible, to people standing in the United States.
