The life of one of Vienna’s foremost patrons of art. This book focuses on Prince Johann Adam Andreas I of Liechtenstein (1657–1712). His skillful economic policies enabled him to increase his fortune, with which he purchased important artworks, invested in building projects and their artistic design, founded a city district, and developed Italian art and architecture in Vienna in around 1700. The prince was an important individual in his dynasty and a great patron and builder. He reorganized administrative structures and invested in businesses and innovative production techniques. He thus created the financial basis for the expansion of the art collection and the construction and furnishing of imposing buildings. To this day, the Gartenpalais and Stadtpalais in Vienna bear witness to the activities of this prince known as a Hercules of the arts.
