Schloss Rosenau hosts seminars, company parties and weddings, with a main hall that takes up to 100 people and a four-star superior hotel on the same site. The castle stands in Rosenau, a small place near Zwettl in the Waldviertel, in Lower Austria. One team runs the hotel, the café-restaurant and the event rooms, so an organiser deals with a single contact.
Seminars and company events
The seminar offer rests on three rooms that can be used together: the Festsaal and two galleries. The Festsaal measures 80 square meters and holds up to 100 people. Galerie 1 and Galerie 2 measure 30 square meters each, which suits breakout groups, a registration desk or a quiet working corner. The hotel also lists four separate group rooms on request. The official pages give no names, sizes or capacities for them, so ask for the details when you send your request.
Seminar sessions can also take place outdoors, with direct access from the Festsaal. The castle terrace looks over the grounds, the hunting lodge and the park, and it gives a natural place for a coffee break between sessions.
The official site names meetings, company celebrations and lodge gatherings as the uses of the event rooms. A company with a small leadership retreat, a team workshop or a year-end dinner will find the format described there.
Weddings and receptions
The hotel has a dedicated section for castle weddings, called Schlosshochzeit. The terrace, the rose gardens and the park around the building give couples several outdoor settings for a reception. The official pages do not publish a maximum number of wedding guests, so confirm the figure for your date before you invite anyone.
Rooms and capacities
Festsaal: 80 square meters, up to 100 people. Galerie 1: 30 square meters. Galerie 2: 30 square meters. Four group rooms are available on request. The three main rooms are described as modular, so the layout can change with the size of the group.
Accommodation
The hotel is rated four-star superior and offers suites and rooms. The number of bedrooms is not stated on the official pages. Check it before you plan a residential seminar or a wedding weekend where every guest stays on site.
Catering
The kitchen follows the regional cuisine of the Waldviertel. A café-restaurant operates inside the castle, and the same management handles hotel stays and events, so meals and meeting rooms can be arranged together. Menus and catering formats are not detailed on the pages we read.
History and setting
Rosenau is a baroque castle surrounded by an estate farm settlement, rose gardens and a park. It also houses the Austrian Freemasons Museum, run by the Museumsverein Schloss Rosenau. The museum presents a ritual room dating from 1748, described as the oldest Masonic temple in continental Europe, where meetings still take place. The castle revealed this part of its past only in the 1970s, when the lodge room came to light. A visit to the museum can fill a free hour in a seminar day.
Getting there
The address is Schloss Rosenau 1, 3924 Schloss Rosenau, Lower Austria. The hotel publishes a page on its location and access. Confirm train connections and transfers with the team when you send your request, as the pages used here do not name a station.
