The finale of the annual Flower Festival: A parade of silleteros, or flower bearers, carry heavy, beautifully decorated displays of flowers (silleta) down from the mountainside town of Santa Elena to the city center.

For the 12,000 residents of Comuna 13, the addition of outdoor escalators in 2012 turned a dangerous 28-story hike into a 6-minute stroll to reach the city center. More importantly, this urban innovation helped the destitute community regain control from violence between guerrillas and drug traffickers. By cutting a clear path through the neighborhood, the escalators severed the territorial power of the armed conflict. Now colorfully painted by neighborhood artists, Comuna 13 is a peaceful testament to Medellín's urban transformation.

The lights of Plaza Cisneros stand in a square once known as the city's hub of mass transit. From tradesmen to thieves, the railroad connected all kinds of crowds until its bankruptcy in the 1960s.
