The Spanish missions in Louisiana are part a series of religious outposts established by Spanish Roman Catholics to spread their faith among the local Native Americans.
Mission Nuestra Señora de los Dolores de los Ais 
- Established in 1716-1717 Site now in San Augustine, TX
- Closed in 1773
Mission San Miguel de Linares de los Adaes 
Mission San Miguel de Linares de los Adaes was the fifth mission established in East Texas in 1716–1717. The mission was to serve the Adaes Indian village just 20 miles (32 km) west of the French fort at Natchitoches, Louisiana. At that time the Spanish claimed the Red River to be the eastern boundary of Texas, so the mission was considered part of Spanish Texas despite being in what is now considered Louisiana.
The mission was attached by French soldiers in 1719 and was closed. Three years later, the Marquis de San Miguel de Aguayo reopened the mission, but at a site closer to the Presidio of Los Adaes. The mission remained open until 1773.
