(bilingual edition: English / German) The "Frauen- und Carolinenbad" bathing facility was opened in Baden near Vienna in 1821. Two hundred years after this event, which was significant from the perspective of both culture and economic and architectural history, this book documents the history of the planning and construction of the building, which has been dedicated to the painter Arnulf Rainer since 2009. The Frauenbad is one of the most important Classical buildings in Austria. Its designer, the Frenchman Charles de Moreau (1758–1840), was one of the leading architects of this epoch in Austria. The book communicates the results of new research on the architecture of this key European period between the Enlightenment, revolution, and reaction.
