Schloss Weinstein hosts company parties, client events, club gatherings and weddings in five separate rooms, from a cellar for 16 guests to a barn for up to 100. The castle stands at Schloss Weinstein 219 in Marbach, in the St. Gallen Rhine Valley, among vineyards, and combines a castle tavern, a panorama terrace and several festival rooms.
Seminars and company events
The venue names company parties and client events among the occasions it welcomes, alongside club events, birthdays, christenings, communions, confirmations and weddings. The site does not describe a seminar offer or technical equipment, so organizers planning a working day should ask what is available. For an evening event, the rooms below give a clear range of group sizes: the smallest suits a tasting for a handful of clients, the largest a dinner for a full team.
Weddings and receptions
Civil ceremonies can take place in one of three rooms. The aperitif can be served on the terrace or in the inner courtyard, and a free-form ceremony can be held in the vineyards. The celebration itself fits the Schlappritzi-Saal or the Schloss-Scheune. In June 2016 the castle placed second among Swiss wedding locations in the Swiss Location Award. From May 2027, the team of Rheintal Gastronomie GmbH will look after weddings, and a new brochure presents their offer.
The castle prefers to show the rooms in person and to discuss options on site, without obligation. Room plans for each hall are published on the website, and a banquet documentation can be downloaded.
Rooms and capacities
The Schlosskeller takes tastings of up to 16 people and aperitifs of up to 25. The Torkel-Stübli, the former wine-press room, is set for 10 to 34 people. The Schloss-Wirtschaft, the castle tavern, holds 40 to 70 people. The Schlappritzi-Saal is the baroque hall and takes 30 to 80 people, with four room plans available. The Schloss-Scheune, the barn, is the largest space, for 50 to 100 people, with two plans.
Minimum numbers matter here. Each room has a lower limit as well as an upper one, so a group of 25 fits the Torkel-Stübli but does not reach the minimum of the Schlappritzi-Saal or the tavern.
Catering
The team offers regional cuisine with attentive service, and the castle also runs as a restaurant, with an a la carte menu and reservations. Banquet documentation lists the options for celebrations.
History and setting
The first written mention goes back to Hans Varnbüler in 1375. Ulrich Varnbüler rebuilt the castle in 1479. Around 1550 a stair tower was added, together with the roof structure containing the Ritter-Stübli and the historic kitchen, which still exists. In 1613 the east wing with the baroque Schlappritzi-Saal, named after its builder, was added. The first tavern opened in what is now the Torkel-Stübli around 1850, and the barn dates from a similar period. Johannes Herzog bought the whole estate, including the farm, in 1943.
The setting among vines gives outdoor options for an aperitif or a ceremony, and the panorama terrace belongs to the restaurant side of the castle.
