The first time I went to Menton this place was closed. The second time (2009) it was opened and what a great experience.
Although small this collection is wonderful to see. As I entered the building after lunch (2pm) the wonderful air-con was such a joy. Obviously with so many original paintings it had to be kept cool in the searing heat and it was.
Be careful when you go up the steps not to miss the paintings on the walls. The upstairs gallery gives an interesting incite into Mr Cocteau.
They all left me feeling quite inspired as I left. A lovely way to spend an afternoon in Menton IMO.
Is this your business?
