On the original site of Nikaia which was the old Greek trading post, most of the buildings of interest are from the Renaissance and Baroque periods rather than from the medieval. If you want to see really old stones, take the bus up to Cimiez where you’ll find a Roman Amphitheatre!
Most visits start at the Cours Saleya, home of the famous flower and vegetable market. Not too far away you will find the Baroque churches of Ste-Réperate and Gésu. Palais Lascaris, Genoese in style, has an interesting museum (free of charge). Towards the top of the old town place St-François and place Garibaldi make interesting locations to linger for refreshment!
There are plenty of bars and restaurants here to cater for your thirst quenching culinary needs especially on the Cours Saleya and Place Rossetti. Oh, and don’t forget to treat yourself to some Socca!
Don’t miss: the wonderful panoramic view of the old town which are obtainable from the top of Château Hill.
