L'Orangerie du Manoir hosts seminars, study days, residential retreats, team building and weddings, from a small meeting of a few people to the Orangerie, listed for up to 300 guests on the estate's business page. The venue occupies a 13-hectare property at 1 rue du Gensbourg in Oberhaslach, in Alsace, about 35 minutes from Strasbourg. Sophie and Michael Jaroszewski, the owners, run the estate and reopened it in April 2023 after a full renovation.
Seminars and company events
The estate sells three formats to companies. A half or full study day in a private workspace includes a welcome coffee, lunch and a snack. A self-run meeting format, for 2 to 30 people, comes with breakfast, a fridge stocked with drinks and lunch, sweet and savory snacks, Wi-Fi, flipchart and projector. A two-day residential seminar adds the same services across both days, with guests sleeping on site. Custom programs are also offered.
Team building is run by partner providers: team games, creative workshops and outdoor activities. Hiking trails start from the estate. The owners stay available before and during the event.
Weddings and receptions
Weddings are the other core business. The weekend formula privatizes the whole estate from Saturday, with all spaces, the Saturday night for 50 guests including towels, and set-up and clearing of tables and chairs in the Orangerie. Weddings can also be held midweek, on Wednesdays only. Lay ceremonies take place in the Manor Courtyard under a hundred-year-old sequoia, cocktails behind the Orangerie or at the edge of the ponds, and the day after can continue at the Guinguette Square with a barbecue or tarte flambée evening. A cabin is set aside for the couple's wedding night.

Accommodation
The home page lists four gîtes, four guest rooms and a cabin with 40 beds. The wedding brochure says the estate can sleep up to 50. Units include Le Nid du Verdier, Le Petit Chalet, La Maison du Gardien and three lodges with three bedrooms each.
Catering
For company events the team handles meals, from breakfast and snacks to dinner, and you choose the menu. The meeting formats include lunch and drinks. The wedding brochure does not state whether couples bring their own caterer, so check this point with the owners.
History and setting
The manor was built around 1830 and was long known as the Relais du Gensbourg. The owners say it served as a hunting residence for Wilhelm II, then as a children's preventorium and a holiday camp, before becoming a second home in 2004 and later a wedding venue. The current owners bought it in August 2022, renovated the whole property with French and Alsatian suppliers, and built the orangery, inspired by Baltard's iron and glass halls and presented as the first orangery in the Grand Est region.
Getting there
Oberhaslach lies about 35 minutes by road from Strasbourg. The estate's brochure gives about 35 minutes to the airport and 15 minutes to the nearest train station, with a motorway close by. Ask the owners for shuttle options for groups.
