Renseverket1) (rense = to wash/clean) is the in lack of other words most “prominent” concrete-block in Ny-Ålesund, close to the coastline Northwest of town.
In former days it was used to clean the coal (seperate it from stones and rocks), now it is basically empty.
There is a door on the side facing towards town, which lodges the workshop. If you enter the building from the other side, there is no door, cracks in the floor and falling rocks. You don't want to go in there. The workshop is lit, warm and cosy, so it should be easy to tell the difference
