Where the U.S.–Mexico Border Fence Enters the Pacific

At the western edge of the land border between the United States and Mexico, a steel fence crosses the beach and continues into the Pacific Ocean. On one side are San Diego’s Border Field landscape and the Tijuana Estuary; on the other is the Mexican neighborhood of Playas de Tijuana. Beside the beach, Friendship Park became a place where people separated by the boundary could see relatives, exchange words and sometimes touch. The barrier entering the surf is the most visible part of a much longer story about how that meeting place changed. An early boundary marker here was an obelisk. After the 1848 Treaty of Guadalupe Hidalgo ended the Mexican-American War, a joint commission surveyed the boundary. A marble monument was erected overlooking the Pacific in 1851. It became an attraction in its own right, with visitors traveling to see where the two countries met. Some took pieces of marble as souvenirs, damaging the marker badly enough that it later required repair and a protective enclosure. The act of marking the line had created a destination. On August 18, 1971, First Lady Pat Nixon visited during the dedication of Border Field State Park. The Nixon Presidential Library’s photographic records document the ceremony, a palm-tree planting, mariachi musicians and Nixon greeting people across a barbed-wire fence. Her visit also gave the place a lasting association with international friendship. News accounts and recordings preserve her hope that the fence would not remain for long. The setting made that aspiration unusually tangible: people could stand within sight and hearing of neighbors in another country, beside the same stretch of ocean. During the following decades, the park hosted family gatherings, social occasions and religious services. Its importance came partly from the limits of ordinary travel. For relatives unable to cross and return, meeting at the fence could be the available way to spend time together. The setting did not remove the international boundary, but it allowed a personal encounter at it. The Cultural Landscape Foundation’s history describes a place used for conversation, contact and exchange before successive security projects changed the way visitors could approach. Border enforcement intensified through the 1990s and 2000s. By 2008–09, construction had introduced a second fence and a federal infrastructure corridor between barriers. A reserve planning document describes patrol and maintenance roads, drainage works and additional fencing. This changed the geography of a family visit: reaching the boundary now depended on being admitted through an outer barrier. The coastal fence also acquired the heavy steel bars familiar in later photographs. What appeared from the beach as one line was becoming part of a much more complicated system. Artists responded to that physical change. In 2011, Ana Teresa Fernández staged Borrando la Frontera, or Erasing the Border, at the Tijuana–San Diego fence. She painted a section of the bars pale blue so that, from a particular viewpoint, they seemed to merge with the sky. Documentation shows her working from a ladder in a black dress and heels. The work changed the appearance of the barrier while leaving its structure in place. Its illusion depended on the same setting that makes the coastal fence so striking: a rigid division set against sea and sky. In October 2012, Friendship Park reopened for limited visits after negotiations over public access. KPBS reported that people could again approach the primary fence, but the experience had altered. Dense metal mesh replaced the openings through which visitors had once held hands. People on opposite sides could barely touch fingertips. The report described a father speaking through the barrier to his children after three years apart. Such encounters gave the park a meaning that its small physical area could not convey on a map. Later closures again interrupted those visits. When KPBS interviewed Myrna Gallegos in January 2023, she described nearly twenty years of relying on Friendship Park to see family. Even a touch through the barrier had brought relief. Her memories included dancing and singing with relatives across the boundary; they were also among her last memories of her father, who had died. Her account explained why proposed changes to a fence could become an argument about preserving a family’s remaining place of contact. Construction of replacement barriers resumed in February 2023. The project involved taller walls, and advocates feared that the new structures would obstruct views and further diminish the meeting place. In statements reported by KPBS, Customs and Border Protection described the existing fencing as deteriorated and said the work would improve conditions and permit future access when operationally safe. Those were the agency’s stated intentions. They did not themselves establish that public visits had resumed. The Mexican side had also become a large outdoor canvas. Murals addressed migration, deported veterans, birds and other subjects, turning the infrastructure into a surface for public expression. In August 2023, KPBS documented artists’ concern that replacement work would destroy paintings on the old fence. Artist Enrique Chiu acknowledged that the structure’s owners could replace the surface, while expressing a determination to paint the new wall. The rebuilding therefore affected both the barrier’s function and the cultural record accumulated on it. Another object arrived nearby that same month. On August 13, a three-ton section of the Berlin Wall was installed on the Mexican side of Friendship Park. Its organizers intended the concrete relic to prompt comparisons between barriers and the people living around them. The slab stood close to a functioning international fence, giving visitors a physical reminder that another famous wall had become a historical artifact. It added a new layer to a site already marked by an older boundary monument. By October 2026, California State Parks distinguished the surrounding state park from the federally controlled space between the border walls. Its information pages said the U.S. portion of Friendship Park remained closed to public access, while the Mexican side was accessible through Playas de Tijuana. Older photographs of open gatherings therefore describe a particular period, rather than an unchanged experience. At the beach, the fence still joins the history of the boundary to the everyday lives of the communities beside it: a meeting place repeatedly reshaped around a line extending into the waves.
