Capacity, Facilities & Floor Plans

Employees at the Atrium Hotel Mainz feel close to nature and are committed to your success. The hotel is located in a quiet area on the outskirts of Mainz-Finthen, at the edge of Rheinhessen’s orchards and fields. Whether at the Atrium Conference Centre (ACC) or in our new convention centre, the Atrium Congress Centre (ACC3), you will never be disturbed by traffic noise or noise from other parts of the hotel.


The larger the space, the more the spirit can open up. All rooms have mobile partitions which make them flexible in size and design. They are soundproof and protected, ensuring complete privacy. For meeting breaks, group work or just a breath of fresh air, the Atrium garden or one of our terraces is close at hand.
