Side 1: Chamizal

Chamizal National Memorial celebrates the peaceful settlement of a dispute over the international boundary at El Paso, Texas, and Ciudad Juárez in Mexico. On August 29, 1963, after decades of arguing about who owned a piece of land shaped and reshaped by the meandering Rio Grande river, the question was finally settled by diplomacy and technology. The river was constrained within a concrete channel for 4.3 miles, forming a permanent boundary between the two nations.

The United States set aside a portion of the former Mexican land received through the Chamizal Convention, or treaty, for recreational and cultural use. At Chamizal National Memorial, established in 1974, music, visual arts, dance, drama, and shared history form cultural bridges as strong as the steel that spans over the Rio Grande.

Diagrams of local section of the Rio Grande in 1899, 1963, and Today (top to bottom) show natural and manipulated changes in the river's course with location of the park for context.

Rio Grande

In the 1860s a dispute arose over a section of Mexican farmland known as El Chamizal. Its original northern border was the Rio Grande, the international boundary. The trouble was that the river’s course was shifting southward (top map), so did it still belong to Mexico? Years later, a flood control project cut off a loop of the river, creating Cordova Island—a detached part of Mexico now north of the Rio Grande (center map).

With the sovereignty of El Chamizal unclear and Mexico’s Cordova Island projecting incongruously into El Paso, tensions rose. In the 1960s, technology came to the rescue: a new concrete-lined channel for the Rio Grande was built, bisecting both El Chamizal and Cordova Island (center and bottom maps). The two nations exchanged land, and people and businesses were relocated. Chamizal National Memorial occupies part of old Cordova Island.


The Flow of History

The Treaty of Guadalupe Hidalgo ends the US­-Mexican War; US gains much of its present­day West. Mexico agrees to recognize the Rio Grande as the Texas­-Mexico boundary.


Massive flooding alters the course of the Rio Grande, initiating a hundred­-year-­long dispute about exact position of the international boundary.

International boundary is established at the center of the river’s deepest channel. If river course changes abruptly, the old boundary remains in place.

River channel is straightened to prevent flooding. This creates Cordova Island, a piece of Mexican agricultural land jutting into US territory.


Arbitration of the boundary dispute takes place in downtown El Paso, while blocks away, the Mexican Revolution is underway.

Cordova Island becomes a drinking and smuggling haven. Efforts, including construction of a fence by Mexico, are made to address the issues.

After the Chamizal Convention

The Chamizal Convention was not just a land swap; thousands of US citizens who lived in the disputed area were forced to relocate, along with businesses, places of worship, schools, and social centers. According to the treaty, the US federal government reimbursed residents for their property, moving, and other expenses. Most structures were demolished.

Many Chamizal residents moved to other area neighborhoods while some left for other cities and states. Reaction to the forced relocation was mixed. While people recognized the opportunity to improve their economic conditions or start new lives, they felt injustice and loss when their families and communities were uprooted. These feelings still echo in the hearts and minds of many former Chamizal residents.

Both nations have used the exchanged land for improved roads, schools, public buildings, and parks. The US Congress set aside a portion of the old Cordova Island as Chamizal National Memorial. In this setting the National Park Service and other organizations present activities and exhibits celebrating the people who share the borderlands.

From across a paved plaza you can see a mural painted on three walls of a building. It shows vibrant, active figures depicting peoples and culture of the US-Mexico border.
