Based on culture as a complex system of rules it is too obvious that each rule has a particular range which is only exceptionally congruent with national or natural borders. In general, cultural exchange is not limited by political borders or rivers, forests, seas, or mountains. Those areas are rather transcultural, which is especially true for markets and towns. Dealing with cities like Buenos Aires or Riga, regions like Podlachia (Poland), Northern Ireland, or Bukovina, and the area of the Danube river the case studies give evidence for this thesis. The book will be of interest to researchers and students in the fields of cultural and intercultural studies.
