Good point :)
The walls (basement) are late 19th century bricks-and-mortar, humidity
is probably coming in from above (rain) and the outside, probably a lot
of it coming in from under the wall, as the groundwater is pretty high.

I have already partly dismissed:
* steel water barrier inlets (probably too expensive, the house is old
and around 22m high, pretty (steely) industrial..)
* we can't really excavate the outside to fix from there. Neighbours..
*sigh*

So we have to act on the inside; I'm thinking of some plastic sealing or
similar, but i'm worried about the wall-substance, too.
