CASA Konferenzcenter is located in Alzenau between Hanau and Aschaffenburg, approximately 40 km from Frankfurt airport. The venue is easily accessible from the region due to its direct location on the A45 motorway and proximity to the A3, with ample complimentary parking directly in front of the building. The venue offers one main hall for approximately 112 people in parliamentary layout and smaller meeting rooms for groups of 8–20 people, equipped with modern conference technology including projectors, wireless microphones, document camera, and full blackout capability. Spaces are air-conditioned, well-ventilated, and lit by natural daylight; windows can be darkened with blinds and open directly to the outside. Since 2002, the venue has hosted seminars for tax advisors. CASA has also established itself as a location for weddings, birthday celebrations, and anniversaries, with the advantage of having no neighboring properties.
