The Great Hall is a conference room of over 370 square meters and over 13 meters in height is adorned with marbled columned walls, ornate gold leaf, and embellished plaster. An oak floor compliments a stunning painted ceiling and two large crystal chandeliers at either end of the event room.

This dome, as well as being a striking feature, also creates a feeling of space and light in the room.
