• The list comes from Wikidata (CC0): museums, castles, palaces, cathedrals, parks, gardens, zoos, squares, monuments and other landmarks with their own articles in at least three Wikipedias, the best known first.
• Each place counts for the city it lies closest to by size and distance; the country lists its best known.
• There are no opening hours, tickets or pictures here: the Wikipedia article for each has them.
