Congress Centre
The Hotel Ossa has a wide offer for the organisation of events, conferences, congresses and meetings of any kind. The total conference area is 3500 m2. We offer 18 multipurpose rooms with the capacity from 10 to 180 people and a large theatre for 600 people and Congress Hall for 700 people. The multipurpose Auditorium Maximum can accommodate 1000 people in its conference part. The Auditorium Maximum and Theatre Hall can be combined (reaching the capacity of 1600 people) or separated with movable partition walls.
The names of the rooms have been carefully selected: the Lavender, Cedar, Saffron and Cardamom Rooms derive their names from Mediterranean and Asian plants. Other names very well match the location of the hotel amongst the Masovian forests and meadows – Heather and Blue Cornflower Rooms. The Fireplace Room and Library bring to mind comfort, and hearth and home warmth.
All the rooms have modern technical equipment for efficient presentations, lectures and meetings of any kind. A state-of-the-art audio system and internet access meet the highest requirements. The audio-visual system makes it possible to record conferences and play the soundtrack of any accompanying visual presentation. The system includes cordless microphones, sound mixers, amplifiers, tape recorders, DVD and video recorders and players, ceiling and wall speakers, etc. Moreover there are multimedia overhead projectors and digital visualisers.
