Why travel to cities? Because in cities human life culminates, culture, tradition, history and development are depicted more intensively and we can experience diverse impulses. Many cities are centuries-old witnesses of human history and offer a broad picture of the cultural development of the regions in their architecture, but also in their museums and concert halls. Here, great triumphs, but also tragic fates of human history can be experienced at first hand. Here we can experience how people at all times have tried to develop their lives as a community, to achieve economic and cultural successes, to defy adverse conditions and to anchor the great ideas of their time locally through lively exchange. This can enrich us personally and strengthen us with new impulses, new energy for our own further development.
