The 10th volume marks a special anniversary: precisely 20 years ago, the first book in this series on art in the public spaces of Lower Austria was published. Since then this movement, situated at the interface of landscape, cultural history and architecture, has continued to expand in Lower Austria, the undiminished demand for the issues it addresses being reflected e.g. in the constantly growing number of requests and commissions received by the artists. The 10th volume presents more than 60 temporary and 20 permanently installed, high-quality works from 2009 to 2011. The art theorist Silvia Eiblmayr concentrates on the complex of issues connecting monuments and memory, while the cultural scientist Elke Krasny investigates the relation between culture, public and state in this field, in which Lower Austria is leading the way.
