The Wall in Netherlands.

Three researched records in two cities in the Netherlands, all of them museum displays.

Best accounts for two of them. Between them the sources report one segment of wall.

A further nine listings for the Netherlands 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.
