Congresses, multi-day conferences, product presentations and company parties for 30 up to 2,600 people can be held here. The venue is the Rhein Sieg Forum on Bachstraße in Siegburg, an event and congress center between Cologne and Bonn, run by the town's municipal company Stadtbetriebe Siegburg.
Seminars and company events
The business team sells four main formats: international congresses and large events, business conferences such as strategy meetings and kick-offs, multi-day conferences, and company events from anniversaries and Christmas parties to incentives and product launches. Conference packages are available, as are hybrid set-ups for events with remote participants. The technical options listed include 4K projection, LED walls, sound systems and high-capacity Wi-Fi, and the team cites almost 20 years of experience with business events.
The forum also runs a public program of concerts, theatre and talks, which explains the stage equipment and the acoustic design of both halls.
Rooms and capacities
The Großer Saal is the main hall, with a gallery and an installed stage of 20 by 6 meters that can be extended by a forestage. It seats 1,425 in rows on retractable tiered seating, 774 at parliamentary tables and 530 to 1,060 at banquet tables, and takes 2,600 standing without the gallery. Acoustic walls split it into a medium version, Saalvariante M, with 1,221 seats in rows or 599 at parliamentary tables. The hall has a parquet floor, rigging points, a truss system, a control room on the gallery and daylight that can be fully blacked out.
The Kleiner Saal measures 355 square meters with a 5.80-meter ceiling and floor-to-ceiling windows. It seats 370 in rows or 140 at parliamentary tables, has its own stage in two sizes, and a mobile partition lets it serve as a foyer or a hall. Six conference rooms of 53 to 79 square meters, all air-conditioned with daylight, projector, screen, whiteboards and Wi-Fi, are reached step-free by elevator. Two foyers, of 225 and 510 square meters, host exhibitions, registration and catering, and the green Patio courtyard next to the conference wing can be booked as a private lounge with catering.
Catering
Catering is in-house. The team serves snacks and drinks before, during and after sessions, with pre-ordered food set on reserved tables to avoid queues at breaks. It organises receptions with reserved standing tables and sparkling wine, and prepares menus up to multi-course gala dinners for banquet layouts.
Getting there
The Siegburg/Bonn ICE station is a few minutes' walk away, which puts the forum on the high-speed line between Cologne and Frankfurt. Cologne Bonn Airport is about 16 minutes by train from Siegburg. By road, the A3 and A560 motorways have exits next to the town. The Parkzentrum next to the forum has 360 spaces and is open 24 hours, with registration by license plate.
