In his hometown of Oslo, Ringnes owns restaurants, hotels and museums, and recently donated more than $70 million for the creation of a large sculpture and cultural park, which opened in 2013.

In 2001 he bought the dilapidated Ekeberg Restaurant in Oslo, not far from the place where Edvard Munch painted The Scream.

He has also given Oslo the sculptures Peacock Fountain at the National Theatre station and Kate Moss at the Opera Passage.

At the age of seven, Ringnes developed a hobby after he received an unusual gift from his father: a half-empty Gordon's Gin miniature liquor bottle.

It was this afterthought of a gift that led him on a path towards amassing what is recognized today as the largest mini-bottle collection in the world with over 52,000 miniature liquor bottles commissioned to a three-story museum in Oslo.
