From the point of view of PL it is now perfect. Directly connected by Eurocity train but only since a year or so.

> the museum didn't really do much to let itself known either

Sure. But you can only do so much with probably not even a handful people and limited budget...

The bulk of Polish population is concentrated elsewhere and the closest big cities (Szczecin, Poznan, Wroclaw) are all more than 200 km away. Warsaw or Upper Silesia, with its masses of people, twice as far.

I wouldn't call this perfect...
