In 972 came the first documentary mention of a chapel. It is believed to have served as a pilgrimage place. The village developing here had its first documentary mention in 1217 in a document from the abbot of Hersfeld Abbey, Ludwig I to the Vogt Bertho von Buchenau, in which the place is named as Cruceberc. The chapel served over the centuries that followed as a village church. In the 16th century, the village was forsaken, until the late 17th century when another place, called Unterhaun, arose here. In 1736, the community acquired a new village church. Subsequently, the old chapel up on a bank overlooking the community fell into ruins in this century. In the Middle Ages, the Knights of Buchenau held the Amt of Schildschlag and the court district of Johannesberg as a fief from the Hersfeld Abbey. To these areas belonged many of today's constituent communities. The Abbey also put the knights to work as Vögte. The Vogtei and the court seat lay together with the St. Johannes provost's seat at the Johannesberg. Later, under the Landgraves of Hesse, the administrative areas were ruled from Hauneck Castle, out of which then came the community's name in 1971.
Amalgamations
Through municipal reform on 31 December 1971, the community of Hauneck came into being with the amalgamation of Oberhaun, Rotensee, Sieglos and Unterhaun. In 1972, the formerly self-administering communities of Bodes, Fischbach and Eitra also joined the community.
