The Musée Picasso holds the art Picasso kept for himself: paintings, sculptures, ceramics and fifteen hundred drawings that stayed in his own studios. The vestibule, the great stair and one seventeenth-century salon survive, and Roland Simounet fitted modern galleries into the old rooms without adding a new wing. Diego Giacometti designed the benches, tables and chandeliers you sit among. The house is the Hôtel Salé, finished in 1659 for the man who collected the king's salt tax; salé means salted.
Picasso died without a will, leaving tens of thousands of pieces in his houses and studios. French law lets an estate settle an inheritance bill in artworks instead of money, and under it the state chose first — that choosing is how this collection exists. The heirs had already given France the pictures Picasso bought or swapped from other painters, so you also see what he hung on his own walls. Much of what is here is drawing and print, which cannot sit in daylight, so the display changes. Do not come for the two famous ones: Guernica is in Madrid, the Demoiselles in New York.
