CD Congress Centre Ljubljana boasts 22 multi-purpose conference halls and represents the largest purpose-built convention centre in Slovenia. A big advantage is the diversity of spaces for different convention needs. The largest hall, Gallus, with 2,000 seats, is still today the concept of extraordinary acoustics and is the only hall of this type in Slovenia (Auditorium). With extensive lobby exhibits it has already carried out a number of conferences with large accompanying exhibitions (up to 4,000 m2 of exhibition space). The renovation is now completed, all spaces are adapted to modern technological requirements, making them more useful, more comfortable and more beautiful.
