Castolon began as an Army cavalry post in 1916, during the height of deprdations along the border of Texas that occurred during the Mexican Revolution. After the Army left in 1921, the La Harmonia store opeend in the od Barracks building, and the small cross-border community of Castolon sprang up around it.
The US National Park Service obtained the land for Big Bend National park in 1944, but Castolon continued for another 18 years. By 1961 most of the residents had left this remote area, and store closed.
Today he remnants of La Harmonia Store and the cavalry Post are operated by the National park Service as the Castolon Visitor Center. A display of derelict farming equipment of the farm that used to employ local residents is nearby to explore.

"History of the Castolon Area
In the early 1900s, people began to live and farm along the banks of the Rio Grande, downstream from Santa Elena Canyon. The fields were fertile and the community grew. Farmers in the area raised corn, beans, wheat, squash, tomatoes, and melons. In 1901, Cipriano Hernandez started the first store in the area and sold goods to his neighbors and to the mining community in Terlingua. He operated the store out of his home, which is today known as the Alvino House (named for Alvino Ybarra who lived there with his family from 1918 to 1957).
From about 1912 to 1920, revolution raged in Mexico. Many Mexican families moved north of the river to avoid the bloodshed and bandit raids. The raids, including the Glenn Springs raid in 1916, brought the U.S. military to defend the border. The National Guard established camps at Glenn Springs, La Noria (northeast of Rio Grande Village), Lajitas (west of the park), and Castolon (Camp Santa Helena). In response to a later revolution (the Escobar Rebellion of 1929), the Air Corps established a landing field at nearby Johnson's Ranch.
Camp Santa Helena, established in 1916, utilized troops from the 5th, 6th, and 8th cavalries. The men lived in tents and the construction of a permanent post began in 1919. By the time the buildings were completed in 1920, the Revolution was over, and the men were ordered to roll up their tents and take new assignments elsewhere. The new buildings were most likely never occupied by the soldiers. They included an enlisted mens' barrack, officers' and non-commissioned officers' quarters, a latrine, a granary and tack shed, and a stable (which burned sometime before 1933).
In 1921, the La Harmonia Company Store moved into the new barracks building and began its eighty-year history of serving as a frontier trading post (from 1918 to 1921, the store was located in "Old Castolon" accross from what is today Cottonwood Campground). The La Harmonia Company was also involved in farming and ranching. In the early 1920s, La Harmonia began farming cotton, a not-so-prosperours endeavor that continued for two decades. In 1961, the National Park Service acquired the La Harmonia Company holdings and began operating the store as a concession operation.
In addition to the store, Castolon includes the oldest known adobe structure in Big Bend National Park (the Alvino House), another store building (Old Castolon), and numerous adobe ruins that were once homes for the many Mexican American and Anglo families that lived in the area. There are two cemeteries in the Castolon area."

"For most people, the Castolon area is a place to stop on the way to the spectacular Santa Elena Canyon. But for those who take the time, it can be a great place to explore the human history of Big Bend. Castolon is certainly not the only area in the park that is historically significant, but it is perhaps the most intact. A trip to Castolon is, in many ways, a journey back in time, albeit to a time not too long ago. Castolon’s history is really not that “old”—farming and ranching continued in the area until 1961. The Castolon Historic District is listed on the National Register of Historic Places."
The Castolon Historic District is also known as: La Harmonica Ranch, Camp Santa Helena; Castolon Army Compound
The Castolon Historic District is located along the Rio Grande River at the intersection of park Roads 5, 9, and 35 in Big Bend National Park, Brewster County, TX
