La Lomita Chapel is a historic Catholic chapel in Mission, Texas. It was once an important site for the Cavalry of Christ, a group of priests who traveled long distances on horseback to minister to Catholics living on isolated ranches along the Rio Grande. In 2018, the chapel became the subject of a dispute between the United States government and the Catholic Church due to the Trump administration's proposal to seize the chapel's land for the border wall between the U.S. and Mexico. In 2019, the proposed seizure was blocked by a budget provision enacted by Congress.
