In Presidio County, a historic marker commemorates the 1918 Porvenir Massacre, where 15 Mexican Americans were killed. This site may soon be more difficult to access due to new border wall construction. The construction could limit access to the marker, which serves as a reminder of the tragic event.

Further details about the potential impact of the border wall on the site are available from the Texas Standard. For those interested in learning more about the situation, additional information can be found through the Texas Standard, which reported on the issue on August 11, 2026.
