Jeziorki Cemetery

Zabytek.pl (https://zabytek.pl/en/obiekty/cmentarz-ewangelicki-672258) gives this description of the Jeziorki cemetery in an undated report (my guess is that this was authored in the mid- to late- 1980s).

At the point of the report, the cemetery had deteriorated to a degree so that dating the place was made impossible but the estimate was made of a 19th century establishment.  The area was approximately .25 hectares.  The place was described as located on the northern slope of the hill, about 100 m from the road.  It was almost a perfect square and covered in vegetation.  The tombstones only existed in fragments and the place was in progressive deterioration.

This schematic drawing is included in the report:

And this photo of an old gravestone is also included.  It's a very interesting photo of a stone but likely from the 19th century.  I can see that it's written in German but I cannot read many words.  It's likely a Lutheran-era stone.

These are some views of the cemetery taken over the last few years (2019-2024)

The cemetery is basically bordered by trees.  Inside the ring of trees, the floor of the place is covered with weeds and lilacs.

Only one stone still stands upright above the undergrowth.

Could this be a fragment of an 18th century, hand-carved gravestone?
