People always assume manholes lead to a massive underground sewer system like the one we saw in Ghostbusters 2, but in truth they can lead to all sorts of interesting places, especially in Milan.
That's where Italian artist Biancoshock has been busy converting the spaces below manholes and the other metal shutter doors you sometimes see in the middle of the sidewalks, into little secret rooms.
Biancoshock's street art series "Borderlife" is truly underground, and aside from the slight danger to public safety posed by these open manhole covers they're sure to make Milan feel like an even more magical place.
Each little secret space has the comforts of home, and if Milan's gnome population suddenly finds themselves homeless they can move right in to Biancoshock's small artsy spaces!
