Old imperial Europe
Paris, Rome, the Riviera. Boulevards built by people who expected to be looked at.
Capital of the Turquoise Coast — a Roman harbor that's still a working harbor, ringed by an Ottoman old town that bends down to the water.
A Seljuk-era castle on a high peninsula, a long crescent beach below, and a Cleopatra-legend swimming cove the locals will tell you Mark Antony actually paid for.
The city that ran the Enlightenment, then the Revolution, then most of Europe's idea of beauty. Walk it. The Métro is for emergencies.
Antiquity in the foundations, Renaissance in the churches, Baroque in the fountains, Vespas in the rest. Walk it backwards through time.
The Côte d'Azur capital that's actually a city — Italianate old town, ochre buildings, a five-kilometer beachfront promenade, and a museum density most capitals would envy.
