Château d'Osthoffen hosts weddings, receptions, product presentations and company events for up to 160 guests at a cocktail in its rooms, and up to 280 seated in a marquee in the park from late April to early October. The castle stands at Osthoffen, in the Bas-Rhin, about 15 minutes from the center of Strasbourg. It is a private family home, lived in by the same family for 200 years, which also rents a few guest rooms.
Seminars and company events
The castle offers its rooms to private and public companies for commercial communication, product launches and corporate receptions. In theater layout, the vaulted Salle des Gardes seats 150, the Galerie 50, the Salon Vénitien 40 and the Salon Blanc 30. A day meeting for 40 to 150 people can therefore run in one room, with a second room for breaks or lunch. Strasbourg airport is 12 minutes away by road, which helps for groups flying in for a single day.
Weddings and receptions
Weddings and private receptions are the core of the castle's event business. The Galerie and the Salle des Gardes each take 100 guests at a banquet and 160 at a cocktail. From late April to early October, the castle sets up a 300 m² marquee in the park for 280 guests seated at round tables of eight to ten, with a dance floor. The marquee is heated in spring and autumn and has its own kitchen area and restrooms. The castle states that its capacity can be doubled or tripled with extra tents on the terrace or in the dry moats.

Accommodation
The castle rents guest rooms named after the people who lived in them, with their portraits, prints and objects. The booking page lists five rooms, from a 14 m² single to doubles of 32 to 39 m², each with a private bathroom and breakfast included. The castle points out that it is a family house and not a hotel, so larger groups will need hotels in Strasbourg or nearby.
Catering
The castle has no restaurant. Breakfast is served to room guests, and the marquee comes with a kitchen and service area for the chosen caterer. The village has a restaurant 500 meters away, with about ten more within 5 km.
History and setting
The present castle grew from a 12th-century fortress on a site that the family traces back to the Roman period. The Bishop of Strasbourg besieged and ruined it in 1410, and it was rebuilt by the architect von Seebach. It became a residence in the 18th century, was badly damaged during the Revolution and was bought in 1817 by General François Grouvel. The Grouvel generals rebuilt the bridge, towers, salons and roof over the first half of the 19th century, and their heirs still live there. In the 1950s and 1960s the castle hosted receptions and concerts held by the city of Strasbourg for members of the Council of Europe.
