Your company event in the most beautiful penthouse in Vienna, wolke21!

The wolke21 in the Saturn Tower impresses with its penthouse character. The location extends compactly on one level - the sky lobby, our lecture room with 160m² and adjoining our event terrace of the same size, a foyer area for registration, get-together and aperitif or for a buffet, a 50m² bar area and finally a cloakroom and toilets that shouldn't be missing either.

For presentations and lectures, we recommend our modern cabaret style seating for around 30-80 people, at high tables and bar stools, up to 180 guests can give a speaker or cabaret artist their full attention, parties - whether in the context of a congress or a company anniversary are possible for up to 280 people.

It is best to plan your Christmas party or your company dinner at round gala tables with up to 130 guests. Of course, we also successfully implement workshops and seminars with a U-shape (around 30 participants) and with theater style seating (around 130 people).

Impress your customers with the unique WOW effect of a penthouse - the doors of the elevators open on the 21st floor and reveal a fantastic, incomparable 360 ​​° view over Vienna from one second to the next! The first impression is always decisive, isn't it?

Weddings or birthday celebrations in wolke21, the most beautiful rooftop location Vienna has to offer.

Imagine if your best friend had given you his penthouse for the best start to your future life together! This "cozy homely feeling" arises as soon as you enter wolke21 in the Saturn Tower.

Your guests can enjoy their aperitif on the terrace or in the bar area above the rooftops of Vienna and with the Danube City Sky Line in front of them. In our “living room”, the 160m² Sky Lobby, 10 to around 130 people can be seated at round gala tables, with a corresponding dance floor, of course. We have conveniently hidden a screen and projector in the ceiling, it is available at the push of a button if you are surprised by your best man or parents with a video or a presentation.

Ceremonies can of course also be planned, with registrars via the MA63 - the department for dream weddings, with a free speaker or according to your individual wishes. Our 160m² event terrace with a wonderful view over the Danube Park offers the ideal setting for this.

After-wedding parties with up to 280 guests can also be wonderfully realized in wolke21.

Enjoy romantic sunsets with your loved ones and dance until sunrise in a very special atmosphere that wolke21 conveys like no other rooftop location in the city.
