Unterburg Fronhausen

Fronhausen, Germany, Germany

---

Unterburg Fronhausen is a Gothic-style moated castle turned manor house on the northeastern edge of Fronhausen in Hesse, Germany, originally constructed in 1367 by Craft Vogt von Fronhausen as a separate seat after a family inheritance split from the nearby Oberburg.

Enfeoffed by Landgrave Heinrich II of Hesse and later passing to noble families including the Schenken von Schweinsberg before entering Hessian state ownership in 1589 as the Schultheiß's office, it features a massive two-story main building measuring 25.5 by 9.5 meters with a Baroque mansard roof, connected via a stone gatehouse to a half-timbered farm structure, its former moats now landscaped as a park.

Damaged in the Thirty Years' War and used agriculturally until 1917 when repurchased by the Schenken, the preserved complex stands privately along Burgstraße, blending medieval defensive origins with later residential utility amid the Lahn Valley landscape.
