In my neighborhood there used to be a huge factory belonging to OM, a very old truck company (founded 1917). Milan is an industrial city, and OM is very much a part of the history of the city, and the factory has been a landmark of this part of the city.
The factory shut down at some point, and was a ruin for a long time. A few years ago the whole area was demolished and a big renovation project was created; housing and office blocks were built, with green spaces and all that.
A large part of that area has been dedicated to three parks. One of them is very appropriately known as "Industrial Memories Park" and is dedicated to the memory of the men and women that have worked in this area.
They kept some machinery from the old factory and build a garden in and on and around the. From an industrial world a new world is born where iron tools mingle with nature in a new embrace.
