 During the Early Middle Ages, cemeteries were located in Steinacker (7th Century) and in Saalbünten (now part of the church, probably from the 8th-10th Centuries).These finds cast doubt on the traditional idea that Aesch grew out of the 12th Century church farm that belonged to the church of Pfeffingen.Frohberg Castle was first mentioned in 1292, but by 1356 was in decline.
