During these last years, the whole world speaks more and more about social segregation, physical barriers to place between the boundaries and division between human beings. In the South American continent, one of the main social problems is undoubtedly the demographic increase of its population and consequently the expansion and crowding of the main cities, which over time have turned into real metropolises. In Peru, this problem is more than ever present in Lima, which with nearly 11 million inhabitants is one of the most populated cities in South America. Most Peruvians moved to the capital in search of better job opportunities in order to satisfy the needs of their families, others to start their business in the economic center of the Country. Over time, this phenomenon has led to the intensification of a latent social problem in every major city: the coexistence between people of different socio-economic classes. This phenomenon caused that the inhabitants of the wealthiest area of the city, feeling threatened by such closeness, have developed the desire for detachment towards the most humble people, due largely to the delinquency and the risk of being a victim of it, deciding to take a position and detach themselves from that part of the city, which according to them, did not reflect their lifestyle. The most singular case of this phenomenon occurred between the district of Santiago de Surco (one of the most exclusive of the city) and the district of San Juan de Miraflores (one of the most humble of the city) where because of this segregation, it has been constructed a concrete wall that physically divides these two opposite realities. The aspect of this wall, similar to a small fortress, leads to think that it hasn't been built only for matters of demarcation, but also for issues of "social separation" since its height varies from 2 to 3 meters, and is equipped with barbed wire. Ignoring the problems or erecting barriers to separate and not seeing the other realities, will never help to create a cohesive society where everyone has the same opportunities, but would only help to widen increasingly the gap between human beings.
