I was told by my guide that it was a replica..... the real Lucy is in a much safer place.....

No but if you Ask they might be able to store it somewhere for you but personally with all the security checks getting in I’d say your better leaving it at your hotel

Le squelette le plus ancient, si je me souviens correctement.

Yes, the National Museum is open all days of the week including public holidays!

Hi, no problem. Free to take pictures

Depends on. If you are very interested in Ethiopia History and Archaeology, you spend about 2 hour once you will read every explanation about each item. But if you just want see and go, you'll spend about 30 or 40 minutes. Where I spent more time was at Archaeology area, because I read every text. Anyway, is a place worthy to see, once there is Lucy, the oldest complete human skeleton
