Costilla County was the first area of the state of Colorado to be colonized with recorded history dating back to 1540, the year Coronado explored the Southwest. It is home to the oldest town in Colorado, San Luis.
Costilla County has two incorporated towns and several smaller communities. The towns of San Luis and Blanca are incorporated while Fort Garland is one of the county’s larger towns though not incorporated. Chama, San Pedro, Los Fuertes, Garcia, Jaroso, San Francisco, San Acacio, and Mesita, are smaller communities, all of which were established shortly after the town of San Luis in 1851.
