Bucharest: The hidden orphans of an unfinished revolution
« We are nobody's children, the children of the sewers. But we are free. »— Bruce Lee (Florin Hora), leader of the 'sewer children', 1990
Under Nicolae Ceaușescu's communist regime, Decree 770 of 1966, banning abortion and contraception, led to a demographic explosion and a dramatic overcrowding of orphanages. Thousands of children, often malnourished and deprived of affection, grew up in institutions where living conditions were inhumane, never knowing the outside world or the warmth of a family.
With the 1989 Revolution, the fall of the regime, and the disorganization of social services, many of these orphans, by then adolescents, were left to their own devices. They found refuge in Bucharest's labyrinthine network of heating tunnels, creating a 'city beneath the city'. This phenomenon of 'sewer children', widely covered by international media, revealed the hidden face of a Romania in full transition, where survival depended on a sense of community and charismatic figures like Florin Hora, known as 'Bruce Lee'.
