(1) Background: Rural areas are characterised by a higher number of volunteers compared to urban centres in Germany. In this context, cultural and arts education is one of the largest voluntary sectors. However, an increasing decline in (cultural) volunteering can be observed. To counteract the decrease, it is important to strengthen regional cooperation and social networks, which are based on trust. The connection between trust, volunteering, and social networks has already been examined, but we still do not fully understand the emergence of trust in the link of cultural education cooperation and networks in rural areas. (2) Methods: A total of 34 semi-structured interviews in combination with egocentric network maps were conducted in four rural regions. The interview data were audio-recorded, transcribed, and analysed using qualitative content analysis. (3) Results: Four dimensions of trust-building were identified: 1. presence and spatial proximity, 2. multiplexity, 3. third party, and 4. community spirit.
