Monaco-Ville

1. 6th century BCE

   Greek Anchor at Monoikos

   Phocaean sailors carved a harbor stop on this sheer limestone outcrop and named it Monoikos after their temple to Hercules. The rock offered the only natural shelter between Genoa and Marseille. For centuries the smell of pine resin and fish smoke hung over its small stone quay.

2. 1191

   Genoa Claims the Rock

   Holy Roman Emperor Henry VI handed suzerainty of the harbor and promontory to the Republic of Genoa. Within two decades the Genoese began building a fortress with four towers and thirty-seven sections of rampart. The walls rose so fast that local limestone dust still clouded the air months later.

3. 1215

   Fortress Rises on the Rock

   Under Fulco del Cassello the Genoese completed their citadel. The structure could hold a thousand men and a 15,000-cubic-metre cistern. Its shadow fell across the harbor each afternoon like a permanent claim.

4. 1297

   François Grimaldi Takes the Gate

   On a freezing January night François Grimaldi, dressed as a Franciscan monk, knocked at the fortress gate. Once inside he drew his sword. The Grimaldi family has ruled from that same rock ever since. Locals still call him Malizia — the Cunning One.

5. 1331

   Charles I Claims Lordship

   Charles I Grimaldi formally assumed lordship of the Rock. He secured Menton in 1346 and Roquebrune in 1355, creating the tiny territory that still exists. The family would never again be mere pirates.

6. 1523

   Honoré I Builds the Cistern

   Honoré I expanded the ramparts and carved an enormous cistern beneath the palace. Its 15,000 cubic metres of rainwater could sustain the garrison through long sieges. Engineers still marvel at the engineering; the water ran clear four centuries later.

Who lived here

• Princess of Monaco · 1929–1982

  Grace Kelly

  Lived here 1956–1982

  The Hollywood star stepped off the Constitution in 1956 and straight into a life few understood. She raised her children in the Palace apartments whose frescoes she personally helped restore. Today her tomb in the Cathedral draws more visitors than any state ceremony — the quiet American who became the Rock's most watched resident.

• Prince of Monaco · 1923–2005

  Rainier III

  Ruled here 1949–2005

  He inherited a sleepy tax haven and turned it into a modern state while refusing to let it lose its soul. The man who married Grace spent decades restoring the Prince's Palace brick by brick. Walk the ramparts at night and you still feel his stubborn belief that this 2km² patch of rock should remain a real country, not just a playground.
