Origin and history

The château du Haut-Barr, mentioned since 1112 under the name Borre (derived from the Celtic bor meaning "height"), was built in the 12th century by the bishops of Strasbourg to oversee the Zorn valley and the plain of Alsace. Its location on a rocky spur at 450 m above sea level, between the Vosges and the Zorn, it is worth the medieval nickname Oculus Alsatiæ ("the eye of Alsace"). The site, consisting of three sandstone rocks with imposing dimensions (up to 80 m long), offers panoramic views and military control over the Lorrain and Alsatian axes.

The initial construction, in local sandstone, began around 1170 with a dungeon and a Romanesque chapel. The castle was renovated in the 14th century (addition of a tower of the well, a north gate and a Gothic choir for the chapel) and in the 16th century (west bastillon, cellar in 1527, round tower between 1544-1551). Between 1582 and 1591 Bishop Jean de Manderscheid founded the Confrérie de la Corne, a drinking company, and modernized the defences (large north bastion, apartments). The castle, partially dismantled in 1649, houses a station of the Chappe telegraph in 1798, moved in 1810 for security reasons.

Ranked a historic monument in 1874, the Haut-Barr is now in ruins, but its chapel (restored several times) and the remains of the ramparts testify to its strategic role. The site also preserves artifacts such as medieval call horns and a reconstruction of the Chappe Tower. Its history reflects regional conflicts, from feudal wars to post-Revolution dismantling, as well as its adaptation to technologies (optic telegraph).

Toponymically, the name evolves from Borre (1112) to Haut-Barr (German Hohbarr influence in the 16th century), reflecting linguistic and political changes in Alsace. The local sandstone, the main material, has various strata: a resistant poudingue at the top ("poudingue savernien") and a fine sandstone at the bottom, shaping architecture according to the epochs (a careful Romanesque apparatus vs. more rustic Gothic).

The castle is part of a dense castral network with the castles of Geroldseck and Greifenstein, illustrating the military importance of the region. Abandoned around 1770 but occupied until the Revolution, it symbolizes both the episcopal power of Strasbourg and the technical changes (renaissance defenses, telegraph).
