A website ran by Henk Vanrensbergen
that includes photo galleries of his adventures.
From the website:
Old factories, abandoned buildings, industrial palaces overgrown with plants and trees, the remaining walls decorated with graffiti, smashed windows, rain dripping through the roof...
These places have become hard to find, difficult (or illegal) to access, dangerous to explore ... great to spend the day!
