Schwalenberg, today part of Schieder-Schwalenberg, was first mentioned in writing in 1127. Situated on a hill above the village is Schwalenberg Castle, which was built from 1228 to 1231.

The Protestant Reformed parish church, formerly St. John the Baptist, was built as a hall church after a fire in 1307, probably the successor to the original monastery church of the Cistercian monastery of Burghagen, which was moved to Falkenhagen in 1247.
