H4MM was founded in 2015 by street artist Kiddy Citny and HUMATIC. The original name “Herz 4 Mauer Museum”. flirted with a term from the German social system (Hartz4) and arose from the gallery's location directly at the former wall where Kiddy's world-famous wall paintings were created. Later the space was renamed to H4 Media Museum and now presents selected works of international creatives at irregular intervals and opens on request to give insights into the diverse works of the HUMATIC team and Partners.
