We stayed an extra day in Nice in order to tour Monaco and Villefranche. We really enjoyed our visit to both places.
The Citadel, a 16th century coastal fortification built by the House of Savoy, is now used mostly for a center of arts and culture. A reminder of its long history as a military post is a motto displayed just inside the main gate: "Chasseur un jour. Chasseur toujours!"
We flew from Nice to Venice to begin Rick's My Way Italy Tour. When we took off we had a wonderful view of the Riviera.
