Wyniger Downtown Basel is an event hall at Henric Petri-Strasse 9a in central Basel, for up to 500 guests. It offers 1,150 m² of event space that can be divided into one to three rooms. The hall is air-conditioned, on the ground floor and lit by daylight. It is run by Wyniger Catering & Events, part of the Basel Wyniger group, which also provides catering and event organization. Organisers use it for company events, seminars, general meetings, exhibitions, anniversaries, Christmas dinners and private celebrations.
Seminars and company events
The operator lists company events, seminars and training, anniversaries, general meetings, trade fairs and exhibitions, and Christmas dinners with a party. The hall suits these formats for several reasons. It is on one level, which makes setup, catering and access simple. It is air-conditioned, which helps in long presentations and focused meetings. Daylight gives a bright setting for product presentations. The site also states that the location is in the city center, with short distances for teams, clients and guests.
The divisible surface lets you match the space to the group. A seminar can use one or two rooms while the rest stays closed, and a larger event can open the whole hall. The site describes the operator's offer for general meetings as professional infrastructure, flexible room concepts, technical and presentation solutions, reception and catering, and personal support on site. For seminars it lists modern infrastructure, flexible room sizes and a quiet working atmosphere.
Weddings and receptions
Weddings and private celebrations are part of the operator's range, and private events are listed for this hall. The operator describes individual room concepts, culinary support and flexible event design. The site shows a 360 degree view and a floor plan of the hall on the venue page, which helps when you plan a seating layout.
Rooms and capacities
The hall has 1,150 m² of event space and holds up to 500 people. It can be split into one, two or three rooms. The pages reviewed give no separate capacities for each part, so ask the team how many guests fit in each configuration and for which seating style.
The operator also runs a second location, Klybeck 610, a former industrial hall of 1,500 m² with several rooms. It is a separate venue and is not covered here.
Catering
Two options are described. In the full-service option, Wyniger Events and Ryago AG provide the food from an apéro riche to a gala dinner, and can organize hostesses, hotels and entertainment, all from one provider. In the individual option, you rent the location only and bring your own caterer, with full freedom for your own service providers. The hall also runs a weekday lunch service for the public.
History and setting
The hall is described as a new event location for demanding events in the inner city. It stands on Henric Petri-Strasse in Basel, in the center of the city.
