Cimiez
Cimiez is an upper class neighborhood in Nice which, apart from some very nice housing, contains among other things the famous Matisse Museum and the Roman Ruins.

Close to the ruins is what is left of the once splendid Hotel Régina where Queen Empress Victoria spent part of her long visits to the Riviera.
