Project origin. This started on Dalhousie’s Agricultural Campus in Truro, Nova Scotia, after noticing six Berlin Wall remnants standing together and asking a simple question: how many pieces of the Wall ended up around the world?

With help from ChatGPT 5.5, the Wikipedia List of Berlin Wall segments was turned into a structured dataset, a Leaflet world map, a sortable table, and a small dashboard suitable for publishing with GitHub Pages.

The dataset treats Wikipedia as the working source. Counts mean listed wall pieces. Wikipedia uses mixed wording such as segments, sections, pieces, and fragments; these are not necessarily identical full concrete wall panels. Where Wikipedia does not state a count, the project defaults to one listed piece.
