History

The Town of San Luis is centuries younger than the pueblos and villages of northern New Mexico because Hispanic settlers were wary of venturing north of the 37th parallel north for fear of Ute and Comanche raids. Armed traders traveled the Old Spanish Trail through the area in the early 19th century. In 1821, the Treaty of Córdoba recognized the independence of Mexico from the Spanish Empire. San Luis was in Sangre de Cristo Land Grant awarded by the government of New Mexico to the Carlos Beaubien family in 1843. The Treaty of Guadalupe Hidalgo annexed northern Mexico to the United States in 1848, and the Compromise of 1850 created the U.S. Territory of New Mexico.

Hispanic settlers from the Taos Valley established several small villages along the Rio Culebra in the San Luis Valley and officially took possession of this portion of the Sangre de Cristo Land Grant on April 9, 1851. The settlers built a church in the central village of La Plaza Medio and dedicated it on the Feast of Saint Louis, June 21, 1851, renaming the village San Luis de la Culebra in honor of the saint.

The United States Army established Fort Massachusetts in 1852 and Fort Garland in 1858 to provide protection for the settlers in the valley. The village of San Luis remained part of the Territory of New Mexico until 1861 when the Territory of Colorado was established. San Luis became the seat of Costilla County in 1863, and remains so to this day. Colonel Christopher “Kit” Carson, Commander of Fort Garland, negotiated a treaty with the Ute people in 1867. Colorado became a state in 1876 and the Town of San Luis was incorporated in 1885. Today, San Luis is the oldest continuously inhabited town in the State of Colorado.

A Pueblo Chieftain article dated June 8, 1872, describes the three stores of San Luis as kept by Fred Meyer & Co, Auguste Lacome and Mazers & Rich in addition to a blacksmith, butcher, beer saloon, carpenter and two hotels.

Today, the town is renowned for its Stations of the Cross ascending the local mesa. The town celebrates the Fiesta de Santiago y Santa Ana each July and the San Luis Manito Christmas celebration in December.
