• Each day starts at the best-known place not yet seen and adds the best known within a short walk of it, then puts them in the shortest order. The places come from Wikidata (CC0), ranked by how many Wikipedias have an article about them.
• The map draws each day’s walk along the streets, routed by Valhalla on OpenStreetMap; the distances beside the stops are straight lines.
• Opening hours, tickets and closures are not checked: each place’s Wikipedia article has them.
