What was the main attraction?

I don't think there technically was a "main attraction". There are probably popular exhibits but none that are the focus of the museum. It's the Museum of Natural History so everything in there is important.

I guess though if I had to pick a main attraction it would be the Pharaoh's Tomb as it had the tablet and all of that intense stuff. Plus, unlike the other beings in the museum (excluding Rexy), Ahkmenrah was a real person instead of a replica.

Actually, most of the museums I've been to DON'T have a main attraction. In the Museum of Natural History in NYC (which I haven't been in in over 30 years), I remember the Hall of Mammals, with it's life sized Blue Whale as a focal point; dinosaur skeletons including a T-Rex (and I want to say a Brontosaurus, but we now know that that was the result of a combination of a couple of dinosaurs); a Hall with dioramas of primitive man; and probably some geology stuff, but that wasn't as interesting to me at that point.

The Museum of Natural History in DC has a main room with an elephant, but there are many halls of that foyer on two different levels including a Hall of Mammals, Sea Life, Gems & Minerals (for my family, the Hope Diamond is the focus of that Hall, but others may find many of the other gems equally compelling). The Air & Space Museum has a central area filled with flying machines ranging from the Wright Flyer to a Pan Am or TWA (I forget which) airliner to several space rockets and a moon rock that the public is allowed to touch - then there are Halls that change every several years (it seems that they rotate). The Museum of American History used to have the central hall with a really cool pendulum clock and the Fort McHenry Flag, but that flag requires better conservation effort and the pendulum is sadly gone. Some galleries are the same for years, others change every year or so. The art museums have no 'central' exhibit. The Native American museum has rooms that each tell a story.

The Holocaust museum is near the Smithsonian 'central area' (the National Mall), and tells many stories within it's story, but there is no main exhibit. The same can be said for the Spy Museum a few blocks away.

It's been almost 35 years since I was in the Louvre, but I don't remember any main exhibit... we saw the Mona Lisa, several Monets, Greek & Roman statues...

Last year I was in a historical museum in Santiago de Cuba and the National Museum of Israel. Again, there were different exhibits based around different aspects of the history of both places, but neither had a 'main exhibit'.

So, my question is, which museums do you speak of?

Museums usually have a main attraction of an artifact.

Was it the dinosaur, or the mummy, or another item
