The Ship That Broke Quarantine: Marseille's Last Plague

The merchant ship Grand-Saint-Antoine dropped anchor in Marseille's harbor on May 25, 1720, its hold heavy with silks and cottons bound for the great fair at Beaucaire. The vessel had sailed from Sidon, with stops at Smyrna and Cyprus — ports where plague was known to be raging. During the voyage, eight crewmen and a passenger had died. The ship's surgeon recorded the cause as "malignant fever." The captain, Jean-Baptiste Chataud, swore the deaths came from bad food and heat.

Marseille's health bureau, the Intendance de Santé, ordered the vessel into the standard quarantine at the island lazaretto of Jarre. Its three-tiered system — among the most rigorous in Europe — required ships from infected ports to remain isolated for forty days, with cargo aired and crews monitored. But the city's merchant elite, terrified of missing the Beaucaire fair and the profits it promised, descended on the intendant's office. They argued that the silk would spoil, that the fair could not wait, that Chataud was a man of honor. Under intense pressure, the intendant yielded. On June 4, the Grand-Saint-Antoine was released. Its cargo moved into the city's warehouses. Its crew dispersed into the streets.

The first deaths

Within days, a porters' child died in the parish of Saint-Martin. Then a washerwoman who had handled the ship's linens. By late June, the mortality bills showed a sharp rise in "fevers with buboes." The disease moved with terrifying speed through the crowded, narrow streets of the old town, where black rats thrived in the refuse and rafters. The intendant, Nicolas de Lamoignon de Bâville, ordered the standard measures: houses sealed with red crosses, watchmen posted, corpses collected at night. But the infection had already slipped the net.

By August, Marseille was losing a thousand people a day. The Hôtel-Dieu hospital overflowed; the dead lay in stairwells and courtyards. Priests and physicians fell in droves. The city's police force melted away — of 120 officers, only a handful remained. The parliament at Aix, the regional capital, fled. The intendant himself retreated to his country estate. In the vacuum, a single figure emerged: Nicolas Roze, a chevalier and former naval officer who had once commanded a galley squadron. He volunteered to organize the removal of the dead.

Chevalier Roze and the corpse brigades

Roze assembled a force of 1,200 men — convicts from the galleys, volunteers, and the desperate poor. They worked in relays, dragging bodies from houses where they had lain for weeks, bloated and crawling with maggots. The stench was so thick that Roze ordered barrels of vinegar and aromatic herbs burned at street corners. The corpses were dumped into open pits at La Charité and Saint-Martin, then covered with quicklime. Of the 1,200 men who joined Roze's brigades, only three survived the summer.

Roze himself contracted the plague in September. He survived, nursed by a servant who refused to abandon him. By then, the disease had spilled beyond the city walls. It raced along the roads to Aix, Arles, and Toulon, carried by fleeing residents and merchants who ignored the cordons. The parliament at Aix, reconvening in emergency session, authorized a measure without precedent: a physical barrier across the countryside.

The plague wall

In October 1720, construction began on the mur de la peste — a dry-stone wall two meters high, stretching twenty-seven kilometers from the Durance River to the Mediterranean, sealing off the whole of Provence from the rest of France. Guard posts were spaced every few hundred meters, manned by troops with orders to shoot anyone attempting to cross. The wall cut through vineyards, olive groves, and village commons. It separated families, halted harvests, and strangled trade. But it held. The plague burned itself out within the cordon, unable to find fresh populations to infect.

The last recorded death in Marseille came in September 1722. The city had lost 50,000 of its 90,000 inhabitants. Another 50,000 perished in the surrounding towns and countryside. The Beaucaire fair, for which the quarantine had been broken, never took place that year — the epidemic had already destroyed the market it was meant to serve.

The end of an era

The Great Plague of Marseille was the last major outbreak of bubonic plague in Western Europe. In the decades that followed, the disease retreated from the continent's ports and cities, lingering only in the eastern Mediterranean and the Russian Empire. The reasons remain debated: stricter quarantine enforcement, the gradual replacement of black rats by less plague-prone brown rats, improvements in urban sanitation, or simply the bacterium's own ecological shifts. But the mur de la peste stood for years after the epidemic ended, a stone testament to a moment when a city's greed opened the door to death, and a wall — built in desperation — finally shut it.
