After visiting Kouvola, we drove to see the UNESCO World Heritage Site, Verla Groundwood and Board Mill (30 km from Kouvola).
Verla is the only World Heritage Site that represents the wood processing industry and Finland's first factory museum. The mill was established 1882 and gradually closed 1964.
We didn't have time to visit the museum. Instead we took a walk around the area.
