Here, the imaginary world of the Smurfs has been recreated in the form of houses with extravagant curves. Behind the Cornavin station, these buildings in their improbable shapes and unexpected colours never fail to surprise! Welcome to the world of the Smurfs!

In the lively Les Grottes quarter, behind the station, there is a strange residential complex with curved walls and surprising colors. Built between 1982 and 1984 by three inspired architects, these buildings recall the work of Spanish artist Gaudi: Balconies in relief, wrought iron railings and, above all, no straight lines. The resemblance between these dwellings and the multi-faceted and colorful mushroom houses in which the little characters in the comic live is the reason why they are called "Smurfs".
