Musée National Gustave-Moreau
This quirky, fascinating place is a 19th-century timewarp, a private home conceived as a museum by the artist owner himself before he died in 1898. Symbolist painter Gustave Moreau bequeathed his house and art collection (not to mention his cabinet of curiosities) to the state, on the condition it was left untouched, preserving his legacy and underscoring his eccentricities for posterity. As well as his masterpieces – fantastical canvases featuring mythological and biblical scenes – you’ll see rare books, drawings, family portraits and a collection of Grand Tour souvenirs. On the upper floor is a rotating display case for watercolours, designed to Moreau’s specifications; the museum is laid out to allow visitors to see as many of the 4,800 drawings and 450 watercolours as possible. The artist’s private apartments are just as crammed with objetcs, paintings and original furniture.
