The Vertical Transformation of Comuna 13

This vantage point offers a striking look at the social and architectural transformation of Medellín, a city that has moved from a history of intense conflict to being a global model for urban innovation. You are looking out from Comuna 13, a district that was once considered one of the most dangerous neighborhoods in the world. Its steep, narrow alleyways made it a strategic stronghold for various armed groups, as the difficult terrain effectively blocked traditional police and military access for decades. One of the most unusual sights here is the juxtaposition of informal, incrementally built homes—characterized by exposed orange brick and rebar—against the high-rise skyline of the Aburrá Valley below. Those vertical steel rods poking out from the rooftops aren’t a sign of unfinished construction; they are a symbol of optimism. In this community, families build their homes as they can afford to, adding a new floor whenever they have the savings. The rebar is left exposed so that the next generation can easily tie in new columns for another level, a practice known as "incremental housing." Directly below, the steep concrete staircases illustrate the daily physical reality of life in the "comuna." For years, these stairs were the only way to reach the upper reaches of the mountainside, requiring residents to carry groceries, building materials, and water up hundreds of steps. To solve this, the city installed a massive system of outdoor electric escalators (las escaleras eléctricas) just a short distance from here. These escalators, alongside the metrocable gondolas you see crossing the valley, have drastically cut commute times and integrated these marginalized hillside communities into the economic heart of the city. What was once a secluded war zone has become a vibrant hub of street art, hip-hop culture, and tourism, proving that thoughtful urban design can radically change the trajectory of a neighborhood.
