History
Medieval origins and reconstruction
Heidwiller Castle is a French castle in Heidwiller, built and developed by medieval noble families from the twelfth century onward. The Lords of Heidwiller are documented from 1105 and were associated with the Counts of Ferrette, a powerful ruling family in southern Alsace. An earthquake in 1356 severely damaged the castle and the surrounding region, including Basel. Reconstruction followed, with the north tower and upper storey remaining as the only original parts. In 1367, ownership passed to the nobles of Morimont.
The Reinach family and the early modern castle
The Reinach family acquired the property in 1486 and held it until the French Revolution. The present castle was built in the early sixteenth century. Its towers later received new openings during the eighteenth century, including arched windows, reflecting alterations to the earlier structure.
Revolutionary use and later ownership
Confiscated during the French Revolution, the castle became a prison during the Reign of Terror, the phase of the Revolution in 1793 and 1794 marked by widespread arrests and imprisonment of suspected opponents. The property was sold as national property in 1795, when its two towers and dependencies were demolished. Bernard Couchepin, then mayor of Heidwiller, bought the property in 1849. It passed to a family of industrialists from Mulhouse in 1862 and was acquired by the Kestner family in 1899. Since 1996, Heidwiller Castle has been registered as a French historical monument, a legal heritage-protection status for historically or architecturally important sites. The protected complex includes the castle and terrace, the park and its archaeological site, the entrance portal, and the grille.
Remains
Castle fabric, grounds, and entrance
The surviving complex brings together the castle, its terrace, the park, and an archaeological site. The post-1356 rebuilding left the north tower and upper storey as the original parts of the castle, while later work added openings to the towers, including arched windows in the eighteenth century. The two towers and the castle dependencies were demolished in 1795, altering the earlier arrangement of the property. The entrance remains marked by a portal and an iron grille forged by the Kestner family in 1899. That gate is still visible within the protected complex.
