In 2010 Comuna 13 was the most dangerous area of Medellín. The territory of drug cartels and gangs for decades. From drug lord Pablo Escobar to FARC and ELN. The neighbourhood has made a huge change since that time, in 2013 the city was proclaimed to the most innovative city of the world and that is mostly to thank for the graffiti. It has brought a new life to Comuna 13.
