Born in Slovenia, Joze Plecnik (1872-1957) was an exceptional architect and urbanist, a person who, through his work, connected cultures. His architectural interventions at the Prague Castle and in Ljubljana, as well as his urban design proposal for Split, demonstrate Plecnik's unmistakable, sensitive approach to history and context. Even in the course of renovations, Plecnik's careful approach uncovered a distinctive language. This monograph reveals new perspectives on the opus of the architect and discusses as yet untreated subjects through the use of texts, as well as photos and plans of his buildings. For the first time, the exhibition "Josip Plecnik - Architecture for the New Democracy," realised at Prague Castle by the author and architect Tomas Valena, a distinguished Plecnik researcher, is documented here. The result is a comprehensive depiction with new perspectives on the work of one of Europe's most exciting architects, who is currently being rediscovered.
