The HIDDEN TREASURE in Bremen is the world’s first black light urban art festival. The artists work together according to predetermined color concepts, using only black and six blacklight colors. From August 18th to 20th August in 2023, over 50 graffiti creators painted the huge outdoor area at the Alte Werft at Stephanikirchenweide 19. As a highlight of the festival, the main wall was completely illuminated with black light at night, creating the largest black light graffiti in the world. Check out the artworks from previous events and the OPEN CALL for 2024.
