Rudolf Kohoutek traverses his city, documenting it with texts and photographs while exploring the intersections between public and private spaces. His aim is not to provide another representation of the iconic Vienna or a nostalgic look at remnants of the past, but rather to offer a subjective yet objective approach as a city researcher to the current state of affairs. In the book "Wiener Grund," text and image sections intertwine chapter by chapter, reflecting the multifaceted perceptions of the city with its moods, colors, spatial figures, and political-economic differences. However, it is more than just an unusual portrait of the Austrian capital: both personal and theoretical aspects of photography, urbanism, and architecture are also addressed. Thus, this "measurement of a love" is not only a reflection on Vienna but on the concept of the city itself.
