Seminars and company events
The Katholisch-Soziales Institut takes conferences of up to 200 people in its largest hall and runs residential seminars with 117 bedrooms on site, in a former Benedictine abbey on the Michaelsberg above Siegburg. The institute belongs to the Archdiocese of Cologne and rents its meeting rooms, hotel and restaurants for outside conferences, training courses and seminars.
The meeting rooms are bright, with daylight, and all come with current presentation equipment; extra technology can be booked on request. Some of the forums open onto loggias or a roof terrace, which gives delegates somewhere to step outside during breaks. Requests go through a dedicated inquiry form, and the team can set up a single plenary day or a program over several days with meals and overnight stays included.
Weddings and receptions
For private celebrations, the institute offers three rooms: the Europaforum for up to 130 guests, the Josef-Frings-Forum for 70 and the Wintergarten for 50, with an outdoor terrace alongside. The team plans celebrations with hosts and shows the rooms by appointment. The website does not present a dedicated wedding package.
Rooms and capacities
The Europaforum, 247 square meters with full-height windows, a parquet floor and a stage, takes up to 200 people. The Anno-Saal, 155 square meters, takes 110. The Edith-Stein-Forum and Seminarraum 8 each take 60, the Joseph-Höffner-Forum 30, and Torhausraum 9, Torhausraum 10 and Seminarraum 03 each take 24. Seminarraum 05 takes 22. The institute adds that seven more meeting rooms sit in the abbey building itself, which helps when a program needs many breakout groups at once.
Accommodation
The abbey holds 117 non-smoking rooms in three categories: Standard rooms of 13 square meters, Komfort rooms of 14 to 17 square meters with a seating corner, and Premium rooms of 33 square meters with a separate lounge area. Four rooms are accessible, with a level-entry shower, and two four-bed units with two bedrooms each suit families. Wi-Fi is free throughout, and the hotel holds a three-star comfort rating.
Catering
Meals are served in the Buffeteria Benedikt, a self-service restaurant suited to seminar lunches, and in the anno17 restaurant, which takes table reservations for dinners.
History and setting
The institute was founded on October 18, 1947, by Cardinal Josef Frings as a center for adult education based on Catholic social teaching. It was based in Bad Honnef from 1952 until early 2017, then moved to the Michaelsberg in April 2017 and opened there in May of that year, in the renovated and extended abbey buildings. A new building, the Forum, was built below the monastery on a former parking area and is linked to the old buildings by two bridges. It holds a restaurant, conference rooms, offices and two parking levels.
