NUEVA JÁEN. Nueva Jáen, in the province of Coahuila, was a short-lived Spanish villa located on the Old San Antonio Road crossing of the Frio River in what is now northwestern Frio County. The settlement, established by Coahuila governor Manuel Antonio Cordero and named after the province of Jáen in Spain, was intended to be the westernmost of several new Spanish settlements along the road east of the Rio Grande. It was established sometime in 1805 but abandoned shortly thereafter due to the lack of an adequate water supply. There is evidence of an unsuccessful attempt by Texas authorities to resurrect the settlement sometime after its abandonment.
