The Wall in Poland.

Poland's records run from a single slab in a village near the Belarusian border to forty-three segments standing in a Silesian meadow, the largest private collection anywhere. Several arrived through partnerships formed in the GDR period, and one marks the estate at Krzyżowa where Kohl and Mazowiecki held a reconciliation mass three days after the border opened.

Ten researched records in eight cities in Poland: six memorials, two private or limited access and two museum displays.

Krzyzowa holds the most, with two records. Between them the sources report 52 segments of wall. A licensed photograph illustrates two of them. Map positions are missing for two of them: either no source supplied one, or the one supplied could not be right.

A further three listings for Poland are held in the catalogue as drafts, out of the map and the indexes until they have been researched.

Every record is labelled Reported: a credible source says the object is there, not that anyone has confirmed it in person. How claims are weighed is set out in the research methodology, and the reading room explains how the Wall came to be spread across places like this at all.
