Schloss Wartegg can host seminars and workshops from 5 to about 80 participants, wedding ceremonies for up to 120 guests and exclusive-use celebrations with all 25 bedrooms. The castle hotel stands in Rorschacherberg above Lake Constance, in the canton of St. Gallen, and describes itself as an organic boutique hotel.
Seminars and company events
The castle offers its rooms for strategy workshops, resilience trainings, team-building seminars and retreats. The seminar rooms are bright and every one of them has a view of the lake. Seating is flexible, so the same room can be set for a small working group or a larger plenary. According to the hotel, rooms suit groups from 5 people up to events of roughly 80 participants.
Each room is equipped with a projector, screens, flipcharts, facilitation material and Wi-Fi. A dedicated seminar website, nachhaltig-tagen.ch, gathers room plans, the price list and the supporting programs in one place. Those programs include guided walks in the castle park and garden, forest bathing, archery, bird watching with an ornithologist and a sailing trip on Lake Constance, which can serve as a team-building afternoon. Company Christmas parties are also listed among current offers.
Weddings and receptions
Several rooms work for a civil or free-form ceremony. The Stiller Raum takes up to 16 people, and the Konzertsaal takes up to 120. The park, laid out in 1860 and covering about 130,000 square meters, can also host an open-air ceremony. An aperitif follows on the south terrace between 2:30 p.m. and 5:30 p.m., with large sun sails and tents as protection from wind and rain.
A smaller format exists for civil weddings: the registry ceremony at 11:00 a.m., an aperitif from 11:30 a.m. and lunch from noon for up to 30 people, on the restaurant terrace in good weather. Other guests may dine in the restaurant at the same time, and the table is available until 4:30 p.m.
For a full wedding, the castle can be used exclusively. On Fridays exclusivity runs from 6:00 p.m. to 10:00 a.m. the next day, and on Saturdays from 2:30 p.m. to 10:00 a.m. the next day. All 25 hotel rooms with breakfast are included, along with the concert hall or park for the ceremony and the banquet hall for the dinner, which seats up to 77. Consumption, additional rooms and extras are billed separately, and a minimum consumption applies to exclusive use. A brunch the following day is available as an option.
Rooms and capacities
The venue lists a Stiller Raum for 16, a Konzertsaal for 120, a Bankettsaal for 77 at dinner, a south terrace for aperitifs and a restaurant terrace for lunch groups of 30. The seminar rooms cover groups from 5 to about 80.
Accommodation
The hotel has 25 rooms. Seminar groups can stay overnight, and the castle offers a private spa with a historic bath and a sauna, useful for an evening break after a workshop day.
Catering
The restaurant cooks seasonal dishes from organic ingredients, many of them from the castle garden. The kitchen handles vegetarian and vegan requests. Banquet menus and aperitif packages are available as downloads on the wedding page.
History and setting
Kaspar Blarer von Wartensee, bailiff of Arbon, built the first castle in 1557 on the site of a former farm estate. Today the building is a stone complex with stepped gables and a prominent tower. The hotel belongs to Swiss Historic Hotels. The park with old trees and the lakeside paths make breaks between sessions easy to organize outdoors.
