Congress Union Celle can take a board meeting for 20, a two-day conference for several hundred or a trade show with vehicles on the floor. The building counts 11 rooms and states a total capacity of up to 3,000 people. It stands in the center of Celle, in Lower Saxony, and has been part of the town since 1909.
Seminars and company events
The venue is built for business events of every size. Small teams use the Kabinett (20 people), the Konferenzraum (26) or the Seminarcenter (40). Mid-sized meetings move to the Schlosszimmer or the Celler Saal, which seats 120 in rows. Large conferences, award nights and company parties go to the Großer Saal, with up to 1,117 seats in rows and 800 guests at a standing reception. The Großer Saal and the Europasaal both accept cars and bulky exhibits, which suits product launches and trade fairs. The venue publishes a day conference package (Tagungspauschale) and offers personal advice on choosing a room.
Weddings and receptions
Weddings take place in the Celler Saal and the Schlosszimmer on the first floor. The Celler Saal seats 100 at long tables or 80 at round banquet tables. Mobile walls open it onto the Wein- & Jagdzimmer, which brings the space to about 263 m² and up to 220 guests. The Schlosszimmer looks out over Celle Castle and seats 50 at banquet tables. The adjoining Kabinett and Konferenzraum can serve as a buffet room or a quiet lounge.
Rooms and capacities
The Großer Saal covers 960 m² under an 11 m ceiling. Movable floor platforms set it in tiers for a show or flat for a banquet or exhibition. Listed layouts: 1,117 in rows, 800 at long tables, 600 in parliament style, 420 at a banquet, 340 in herringbone and 800 standing. The Europasaal (about 370 m², ground floor, 8 m ceiling) seats 400 in rows, 280 at a banquet and 300 at a reception, with step-free access to two foyers with daylight. The Celler Saal measures 149 m². The smaller rooms range from 27 m² for the Kabinett to 75 m² for the Schlosszimmer.
Accommodation
There are no bedrooms in the building. The venue keeps a list of hotels in Celle for delegates and wedding guests, so a residential program is booked in two parts.
Catering
Food and drink come from the house catering team, which also caters events at other sites in and around Celle. Formats run from finger food and small snacks to cold and warm buffets and plated menus, based on fresh, regional and seasonal produce. On site, Thaers Wirtshaus serves salads, Flammkuchen, steaks and currywurst and shows live sport, a practical option for an informal evening after a conference day.
History and setting
The Congress Union has been a fixture of Celle since 1909. The town was a ducal residence, and the Schlosszimmer still looks onto the castle that recalls that period.
Getting there
