By default, this shows just the museums on Wikidata; green ones have an image, red ones have not.
The data updates as you move the map around, or search for a new location. Might be more intuitive than the query service.

I noticed earlier today that most of the museums in Birmingham were
not showing on this query (they are now!):

This was because they were not shown in Wikidata as a museum (or
subclass thereof); some were simply marked as "manor house",
"factory", "water mill", etc. Or it was because they had no "located
in the administrative territorial entity"(P131) property.

You might like to check your local museums, or those you've worked with.
