The above photo is one of a few installations by artist Baincoshock where abandoned manhole covers in the streets of Milan have been turned into tiny, detailed (with wall tiles, artwork etc.) rooms. Although tiny pieces of art in themselves, the installations are a social commentary trying to bring attention to a larger problem that troubles Bucharest: the fact that hundreds (over 600 actually) of people are living underground in the sewer system! A powerful way to bring attention to an important idea–to not forget to speak about the environment around us and the problems that it may face.
