Ancient Polish monuments

mythicalireland.com is an Irish site popular to those interested in the ancient monuments or areas of indigenous spiritual traditions within our landscapes.

I am curious as to whether there are such web/sites in Poland? Can someone suggest one please?

Can someone also tell me the name of the Celtic settlement that was discovered in Southern Poland also?

One is Krak's Mound in Kraków, believed to date from around BC 500. Krak was the name attributed to the legendary king of the forerunners of today's Poles, known as Lusatians. There is disagreement as to their ethnicity, believed by some to have been proto-Germanic.
