Costilla County was one of the original 17 counties created by the
Territory of Colorado. Although San Miguel was originally desinated the
county seat, the county government was moved to San Luis in 1863. The
county's original boundaries had the county extend over much of
south-central Colorado. Much of the northern portion became part of
Saguache County in 1866, and the western portions were folded into
Hinsdale and Rio Grande counties in 1874. Costilla County arrived at
its modern boundaries in 1913 when Alamosa County was created from its
northwest portions (source: wikipedia)
