The Wall in Spain.

Eight researched records in four cities in Spain: three relocated segments, two museum displays and two memorials.

Madrid accounts for four of them. Between them the sources report six segments of wall. A licensed photograph illustrates two of them. Map positions are missing for three of them: either no source supplied one, or the one supplied could not be right.

A further two listings for Spain 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.
