Le Chateau, the shaded hill and park at the eastern end of Quai des États-Unis, is named after a 12th-century château that was razed by Louis XIV in a fit of pique in 1706 and never rebuilt. There are some ruins but not really a chateau to speak of. In the one remaining tower, the 16th century Tour Bellanda, is the Musée Naval. The cemetery where Garibaldi is buried covers the northwest of the park.
From this 300 ft (92 m) hilltop park aslo known as Castel Hill, the glittering views of Vieux Nice spires and the Baie des Anges are mesmerizing. It's worth the walk up - especially as you pass waterfalls, pools and gardens along the way. Once at the top, sit and have a coffee under the trees; the cafe offerings are very much kiosk style but the view makes up for everything.
Near the eastern end of the Quai des Etats-Unis, you will find the steps leading up the hill to the Parc du Chateau. There is also a lift (an ascenseur) for those who don't fancy walking all that way. Or you can ride up on the touristy Petit Train de Nice.
