12 February - 24 August 2010. One of Europe's oldest families of noble lineage, the Princely House of Liechtenstein can be traced back as far as 1136, to Hugo von Liechtenstein who called himself after the castle and region situated south of Vienna. His present-day successor, Prince Hans-Adam II, has revelled in the age-old family tradition that is collecting works of art. His prolific purchases over recent years have seen the collection swell to over 450 paintings. To celebrate his 65th birthday, these treasures are being shown to the public as one giant exhibition.
