Klaus Dona has been the Art Exhibition Curator for over 30 cultural exhibitions in Austria, Japan and Korea, like "The Glory of the House of Habsburg", "Rubens and his time", etc. Being a specialist in culture and art exhibitions, his attention was automatically drawn to a phenomenon called 'Ooparts' - out of place artifacts. These are artifacts that should not exist according to current science. Klaus Dona has been researching these types of artifacts for over a decade and, after a long preparation, decided to set up an exhibition of 470 of these (Ooparts) pieces, which he called ''Unsolved Mysteries''. Klaus will speak about many of his strangest Ooparts, as well as the bones of ancient giants that have been presented to him, and the recent discovery of the remains of a 20 foot tall giant in Bolivia he has been asked to examine.
