The Wall in Bulgaria.

Three researched records in two cities in Bulgaria: two memorials and one artwork.

Sofia accounts for two of them. Between them the sources report two segments of wall. A licensed photograph illustrates two of them.

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.
