Origin and history

The Helfenstein Castle, located in Philippsburg (Moselle), is a medieval castle whose existence was forgotten until it was rediscovered in 1927 by Adolphe Malye. Probably built before the nearby Falkenstein, it would have origins dating back to the 9th or 10th centuries, although its first written mention dates from 1264, as property of the Dukes of Lorraine. The site, located 350 m above sea level, is separated from the Falkenstein by a 100-metre ditch, and the two fortresses seemed deliberately to ignore, a rare but not unique phenomenon in Alsace-Lorraine.

The name Helfenstein could come from the High German medium Helfant (Elephant), with reference to the massive shape of the rock, or from a deformation of Elfenstein (rock of the elves), linked to Germanic folklore associating these creatures with rock formations. Another hypothesis, less retained, evokes the verb Helfen (aide), although the names of castles derived from verbs are rare. The site was also nicknamed Wachtfelse after its disappearance, reflecting its lost strategic role.

The Helfenstein was first mentioned in 1264 as a fief of the Dukes of Lorraine, before moving on to Wasselonne's family. Ravaged by a fire in 1315, he became the target of the Falkenstein lords, leading to a conflict arbitrated by the bishop of Strasbourg. In 1410, he was still cited as a Lorrain fief including the villages of Butten, Kirspach and Birsbach. Around 1435, Guillaume de Falkenstein was seated and destroyed the Helfenstein, opposing its reconstruction. In 1437, the bishop settled a dispute over his ruins, called zerbrochene Feste (fortress dismantled). After 1470, only the name of the mountain remains in the archives.

The castle, never rebuilt, probably served as a stone quarry for the Falkenstein, gradually clearing until it looked like a simple rocky outcrop. His oblivion was such that even the premises did not know his existence at the beginning of the twentieth century. His rediscovery in 1927 by Adolphe Malye, a passionate scholar, was accidental: while he was looking for prehistoric polishers near Falkenstein, he fell on a cubic monolith bearing the traces of a fortress. His research then confirmed the location thanks to forgotten archives, including those of Johann Georg Lehmann (1878).

The remains of the Helfenstein reveal a north enclosure flanked by buildings and a tower, as well as an empty rock sheltering stairs, a cistern and a deep well. Bolt holes attest to a rock-backed wooden structure. A bronze snake found on the site is now on display at Niederbronn-les-Bains Archaeology House. Adolphe Malye's analysis showed that the two neighbouring castles deliberately turned their backs, illustrating local feudal tensions.

The site, though modest, offers a rare testimony to the political and military dynamics of the Northern Vosges in the Middle Ages. Its proximity to the Falkenstein, despite their mutual hostility, underlines the density of seigneurial powers in this border region between Lorraine and Alsace. The oblivion of the Helfenstein also reflects the fragility of the memory of secondary castles, often overshadowed by more prestigious fortresses like his neighbour.
