📜 A City in Place of Rome

The year was 1257.Rome was in turmoil—hostile, dangerous.Pope Alexander IV decided it was time to find a safer refuge for himself and the Curia.He chose Viterbo: strong, loyal, and strategically perfect.

Thus began Viterbo’s great papal season:for 24 years, the city became the beating heart of the Church.The Palazzo dei Papi was expanded, fortified, elevated.

No longer just a refuge—it became a spiritual and political fortress, poised to shape the destiny of Europe.

🛡️ The First Conclave… by Starvation

In 1268, Pope Clement IV died.What followed was the longest and most dramatic conclave in history.Thirty-three months.Three years of infighting, strategies, alliances, betrayals.

The people of Viterbo, exasperated, locked the cardinals in the Conclave Hall.They reduced their food rations.And—legend has it—they even removed the roof, leaving the cardinals exposed to sun and rain, desperate for a decision.

At last, exhausted, the cardinals elected Pope Gregory X.

Thus, the very concept of “conclave” was born:“cum clave”—locked with a key.
