I had to start with the mother of all artistic tourist draws in the world.
Mona Lisa, Leonardo da Vinci (c. 1503)
She’s doubtless the most famous ancient Greek sculpture in the world (with or without arms).
It’s just downright beautiful. Look at how Renoir captured the light!
Bal du moulin de la Galette, Pierre-Auguste Renoir (1876)
There, in two large oval rooms on the ground floor, are installed eight unvarnished oil paintings on 22 panels.
Water Lilies, Claude Monet (c. 1915-1926)
Easily one of the most celebrated and recognizable sculptures ever created.
The Thinker, Auguste Rodin (1906)
