What about PL freemasons and their pyramids in the middle of PL nowhere.
I know that the last Polish king, Stanisław August Poniatowski was a free mason, as well as the first Polish president, Gabriel Narutowicz or the man that appears in Polish national anthem, general Henryk Dąbrowski.
One of the biggest free mason book collections in Europe are gathered at Adam Mickiewicz's University in Poznań. And I also know about one of their past assembly places located in Wielkopolska, so if you are really interested in this stuff you can go and visit it next time you will be here, Fisz. It's in Dobrzyń.
PS: American president that promoted reemergence of independent Poland in the early XX century, Woodrow Wilson, also was a free mason. Coincidence? :) :)
