Contribution guidelines
It is important to us that as many people and communities as possible can share the story of their town, village, or building. The architectural heritage of our region becomes truly complete when the voices of local people are included — those who have known these places for generations, who remember the legends of a church, or who understand the role a building once played in everyday community life.
For this reason, HeritageBuilder.eu functions as an open platform: any user can create entries, upload photos, documents, and contribute their own knowledge. We believe that preserving architectural heritage is a shared responsibility, and we want to give space to everyone who can help enrich the cultural memory of Central and Eastern Europe through their contributions.
