A museum is a public building displaying artworks, historical objects, scientific exhibits, or cultural collections.
Counted, not streamed: Museum has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
