This famous glass pyramid in the Louvre by American architect Yoo Ming Pei is very useful functionally: it's essentially an entrance, and it's greatly reduced the Louvre's clutter. But it's still very controversial.
In my opinion, functional convenience is extremely important, and the architectural solution is a bit simple.

Jakov Trembovolsky (Jak Trum)Thank you. A play of contrasts. It was drizzling in the evening, so I decided to take some pictures in the morning by streetlight. The next day, I showed up at 5 a.m.—the lighting wasn't right, the approach was blocked—so I shot from afar. But then, with a tripod over my shoulder, I trudged from their "Louvre" to the Arch, scaring all the waking locals. (But there's plenty to photograph there, day and night, and in the rain.)

Yes, it's all very interestingly linear
And where are the Japanese?
