Comuna 13 was at one point considered the most dangerous neighborhood in the world, with one of the highest murder rates anywhere. The neighborhood was previously controlled by drug dealers, murderers and guerrillas. The police didn’t dare to enter the neighborhood, and in the evenings, public transportation would stop working and no one could go out or enter the Comuna 13 neighborhood. In October of 2002, about a thousand soldiers, police and special forces invaded the neighborhood accompanied by tanks and the air force and began Operation “Orion” to clean up the neighborhood. The Comuna 13 neighborhood now features thousands of the most beautiful graffiti paintings in the world, and they are the reason that the most dangerous neighborhood in the world became the most touristic neighborhood in Medellin, visited by thousands of tourists every day.
