Château d'Ollwiller, Château and wine estate in Wuenheim, France

Château d'Ollwiller is a heritage château in Wuenheim that operates as a working wine producer growing varieties such as Crémant d'Alsace and Riesling Grand Cru. The estate spans agricultural land with south-facing slopes and uses its marly soil to cultivate wines that carry regional designations.

The estate at Ollwiller is documented from the 13th century as property of the Cistercian abbey of Lieu-Croissant. In 1260 it passed to the Waldner family, who built a moated castle with the Bishop of Strasbourg's consent. Count Dagobert Waldner de Freundstein had the medieval castle demolished and replaced by a Baroque château built by Antoine Mathieu Le Carpentier from 1750 to 1752. French artillery fire destroyed it on 21 December 1915; it was rebuilt in simpler form in 1925, and a fire destroyed its oldest part in May 2011.

The name Ollwiller appears in records as Olwilre (1249), Ollewilre (1254) and Ollinwilr (1291). The estate gives its name to the Alsace Grand Cru Ollwiller, classified in 1983 among the first 25 Alsatian terroirs, and to a Pinot Noir. Since 1959 the domaine has been part of the Cave du Vieil-Armand cooperative.

The château stands about one kilometre south-west of Wuenheim and just over a kilometre west-north-west of Hartmannswiller, on the road towards the Hartmannswillerkopf. The vineyard slopes lie between 260 and 320 metres on a south-south-east incline between the château and the village. The site is a working wine estate, not a public park, so visits are best arranged around wine sales rather than treated as a garden walk.

Only two châteaux in all of Alsace are authorized to market wines under the château denomination, and this property is one of them. This rare approval reflects special recognition of the quality and longevity of the place.
