The association has held events at the venue on various occasions since 1991. It will bring 6,000 delegates to the city in October 2017, then visit Barcelona and a 'wild card' city in between, before returning to Vienna in 2020, with the option of returning every three years after that.
Prior to this, the Austria Center will welcome 9,000 dermatologists for the European Academy of Dermatology and Venereology's (EADV) annual conference from 28 September to 2 October next year.
The event has almost doubled in size since it was last held at the Austria Center back in May 2007, and it will will take over the majority of the city's exhibition spaces. "In total some 11,300sqm of event space and 10,000sqm of exhibition space has been booked for the five-day conference," confirmed sales manager Michael Part.
He added that a number of the meeting rooms leading off the main halls will be transformed into hospitality and sponsor suites, committee meeting rooms, press areas, speaker preview centres and breakout areas.
Susanne Baumann-Söllner, managing director of the Austria Center Vienna, said: "I am really pleased to see that all of our hard work is paying off. The venue is regenerating in front of our eyes – with all new furnishings, newly created areas to relax such as the business lounge and the coffeehouse, a new lighting system in Hall A and a multifunctional screen system throughout the main building and exhibition halls.
"Our tried-and-tested partner organisations and our new catering partner are also doing a great job, which is going down very well with our customers."
