Thank you @triplug . I also visited the Louvre Paris, and yes, you are right, it needs a few visits to cover most of the exhibitions. Louvre Paris is definitely larger in size. To me, the interesting part was the element of surprise when I visited Louvre AD, because simply the building very stands out and looks like out of this world. In comparison, Louvre Paris has a very historical design that blends in well with the city; thus, it's kind of expected.
