The factory is completely surrounded by a new fence to keep vandalists out, so I had to cycle around to get to the claypit.

The complete factory and the tracks (just) visible on the side of the road

This shed was next to the clay pit. All doors locked except the small one (well, actually this was one was locked too, but the doorframe was rotten so it could be pulled open easily). The yellow sign says "dumping waste not allowed" (verboden vuil te storten).

Waste

The claypit. The water level is normally lower, some trees standing in the water. My map actually shows two claypits.

Opening the small door in the shed I found some kind of workshop.

This is what you get if you use a long shuttertime and wave a flashlight about.
