Hi, this is historical grade II listed building known as "Former Leadworks / Leadworks". Thus building has current historic/tourism interest. Previously leadworks wikidata link was added directly to Aquarium amenity. Which in my opinion is incorrect, because "Aquarium" has it's own wikidata tag. Another thought on this - presence of restaurant in the building doesn't always change the building name. That's why in this case I have separated building itself and amenities. In comparison in London "The War Office" evolved to "The Old War Office" and recently changed name / purpose to "The OWO". Back to this case, if you check cadaster you will see that Aquarium also situated in the former Leadworks building. So the more correct way would be to merge all this buildings together and name everything "Aquarium", set old name / alt-name to leadworks and map that VR Lab and Prezzo restaurant just rent a space on the southern part of the Aquarium building. Let me know what you think about this arguments.
