Former sodium factory, Schiedam
We went to visit the factory with the Urban Photo Collective.
The factory was built around 1800. The last years it has been completely neglected but now a number of people are trying to collect funds, restore it and give it a new destination. Check www.sodafabriek.nl for the details (in Dutch only).
The building is normally closed. Don't go in there on your own. It's very dangerous!
