The area of today's Jasień was inhabited as early as the Neolithic period (approx. 3200-1850 years BC). However, the recent history of the town dates back to the turn of the 13th and 14th century. The village had its own church already in the 14th century, which is evidenced by the first mention of the existence of the parish from 1325. The present parish church of The Assumption of the Blessed Virgin Mary was built in 1436 and was founded by Spytko of Melsztyn, Leliwa coat of arms. An interesting polychrome has recently been discovered in the church. There is also a baroque baptismal font carved in stone and a neo-Gothic main altar made in 1930 by sculptor Stanisław Rogóż from Brzesko. From January to May 1915 Jasień was the location of a military airfield. The airfield was for reconnaissance flights and the transport of mail and military reports to the Fortress of Przemyśl.
