ArchTech is an innovative initiative that bridges the gap between European architectural heritage and digital technology, aiming to inspire young people to actively engage with and protect their urban cultural landscape. Rooted in the belief that architectural heritage is a vital element of European identity, the project seeks to enhance awareness of built heritage among youth while promoting digital upskilling and civic participation. By leveraging the popularity of mobile technology, ArchTech empowers youth workers and young individuals, including those from vulnerable backgrounds, to co-create digital tools such as mobile applications and guided digital tours, making heritage more accessible and engaging. Through interdisciplinary training modules, field activities, and community-driven initiatives, the project not only fosters a sense of belonging and responsibility but also aligns with key EU policies on cultural heritage preservation and youth digital education. With a strong collaborative framework across five European countries, the project contributes to an inclusive and technologically adept society where historical preservation and social innovation go hand in hand.
