A short walk from Monet's house, this museum holds changing exhibitions of Impressionist and post-Impressionist work rather than a permanent collection — which means it is worth checking what is showing before making it a priority. The building is modern and well-designed, set in gardens that complement rather than compete with Monet's own.
When the exhibitions are well-chosen — which they often are — the museum offers a welcome counterpoint to the house: it situates Monet in the broader movement and shows what the generation after him did with his ideas. Entry is reasonable, and there is a good café in the garden.
