On 7 February 1965, she married Prince Michael of Greece and Denmark at the Royal Palace in Athens. However, because the marriage was considered non-dynastic, she did not automatically acquire the title of 'Princess of Greece and Denmark' nor the style of 'Her Royal Highness', but is instead referred to as Marína, Consort of Prince Michael of Greece and Denmark.[3]
Karélla began her career in 1966, when she presented her first exhibition of paintings at the Festival of Two Worlds in Italy. Her early career was heavily inspired by themes related to Greece.[3] In the '70s she exhibited her White Paintings at Gallery Ioulas, which are now considered among the most famous pieces of her work.[4] The following decade, Karella put up multiple exhibitions at the Earl McGrath Gallery in New York, which also included collaborations with Jack Pierson.[5] Throughout the '90s her work was featured in multiple publications, including The New Yorker and New York (magazine).[6][7][8][9]
During her career Karélla has put up a number of exhibitions in various cities around the world, such as New York, Los Angeles, Athens, Brussels, Rome, and London, while many of her works are also hosted in many museums and institutions.[4][10] In 2005, a retrospective exhibition of her work was organized at the Benaki Museum in Athens.[11]
In more recent years, Karélla has increasingly ventured into philanthropic works and is currently the founder and president of Eliza, a non-profit society that works towards the prevention of cruelty against children.[12]
