A 17th-century structure, the Lyon Museum of Fine Arts is one of the largest museums in France and in Europe, with over 70 galleries. The museum isn’t just impressive in size. It hosts an enormous collection of works, reaching from classical antiquity to modern art—from the land of Egyptian pharaohs to Gauguin’s autumnal jungles. This online tour takes us through 30 masterpieces, explaining each one in detail. —E.C.
