Years of learning are necessary for the artisan-founders to master precise gestures. Each object requires dexterity, and highly qualified workers are particularly sought-after. Although modern in its forms, street furniture is no exception. The GHM foundry in Sommevoire specializes in art foundry but has also dedicated part of its production to create a range of street furniture since the 1970s. The site perpetuates the common thread of its founder Antoine Durenne to bring art into the cities' streets.
