The recently published ICOMOS working documents show that a big portion of Nice is to be included in this nomination and not only its waterfront promenade. Nice is a major tourist hub in France mostly catering for beach tourists. This can be regarded as a sign of continuity, perpetuating the historic function of Nice in the development of modern tourism. The most significant component, the renowned Promenade des Anglais, I did not find neither very scenic nor authentic. A lot of new buildings on the city side of the road do not allow for a unified cityscape. However, other parts of the city centre, which are all included, are very well preserved.
The mediaeval old town is a typical Ligurian city with dark little alleyways and colourful fronts. Although included in the perimeter, it had little to do with the birth of modern tourism. Its extension in the 19th century includes large avenues and a lot of historicist mansions. They constitute a nice ensemble, but I think it would be difficult to demonstrate their connection to Nice becoming a tourist centre. Cimiez, Nice's Roman antecedent is included too. It now houses two famous museums dedicated to Matisse and Chagall. Although Nice's artistic contribution is mentioned as a part of its OUV, these museums are new and, as with other components, I fail to see the connection to modern tourism.
The beaches of Nice are pebbly. For beach tourism other areas of the French Riviera are surely superior. Culturally, however, it offers a lot for a stay of a few days. I would especially recommend its comprehensive and high quality museum of contemporary art, one of the best in Europe and the second best in France after Centre Pompidour in Paris. Nice is a comfortable hub for day trips along the French Riviera (Grasse, Cannes, Antibes, Saint-Paul/Vence to the east, Eze, Menton, Monaco, Ventimiglia to the west) with many sites that are artistically important (Matisse, Picasso, Fragonard, Le Corbusier, Renoir). Although interesting, I fail to see a great potential for OUV. Moreover, I would highly advise against visiting Nice during peak season.
