The National Museum of Slovenia is the oldest Slovenian museum institution. When its halls and rooms are not in use, they can be hired for various occasions such as presentations, press conferences, concerts and receptions. A standing-room-only reception can be organized in the atrium for 700 guests or a banquet for 200 guests. In summer, it is also possible to organize receptions or performances in the museum lapidarium, and open the glass walls and extend the reception into the garden alongside the museum building.
