In 2013, DILART applied a 17,9 x 13,4 meter large DecoMark® city map in the parc at the Triumphal Arch in Barcelona. Even though, the decorative and informative city map was applied on a challenging stone surface, it is still guiding tourists in Barcelona.
So if you get lost in the area around the Triumphal Arch, then look for the DecoMark® city map.
Here, you can see images right after the application of the Barcelona city map in 2013.
