History of Siena Cathedral
The story of the Siena Cathedral is one of unbridled ambition born from a fierce rivalry. In the medieval period, Siena was locked in a constant power struggle with its neighbour, Florence. The Sienese wanted a symbol of their dominance and piety that would make the world gasp. They looked at their existing cathedral and decided it simply was not grand enough. Their solution was to build a new one, the Duomo Nuovo, that would turn the existing structure into a mere transept of a colossal new building. This was a project of insane scale and confidence, reflecting the economic power and arrogance of a city at its zenith. However, history had a different plan. The grand vision collided with the devastating reality of the 1348 plague. As the Black Death swept through the city, claiming countless lives, the economy crumbled, and the labour force vanished. The grand expansion project was abandoned mid-construction, leaving behind the stark, towering wall that locals call the Facciatone. This structure remains a poignant monument to human ambition, showing just how close Siena came to creating an architectural feat that would have dwarfed almost everything else in Italy. The failure to complete the vision paradoxically preserved the original, more intimate, and exquisitely detailed Gothic masterpiece we see today. Over the following centuries, the cathedral became a canvas for the greatest artists of the age. Because it was never fully finished to the initial massive plan, later generations focused on enriching the interior. They installed the incredible marble floor, commissioned Michelangelo, Pinturicchio, and Donatello to fill the nooks and altars with masterpieces, and integrated the cathedral into the very fabric of Sienese life. Today, it stands not just as a religious site, but as a living diary of the city. When the Palio is won, the cheers of the winning contrada echo within these walls as they sing their thanks, ensuring the cathedral remains the beating heart of Siena, just as its builders originally intended.

This massive, solitary wall of striped marble stands as a haunting monument to the city's thwarted ambitions. It was intended to be the facade of the 'New Cathedral', a project designed to dwarf the existing church, but was abandoned forever when the plague decimated the population in 1348. Today, visitors can climb the narrow, winding stairs inside the wall via the cathedral museum. Reaching the top grants what is arguably the most spectacular, vertigo-inducing view over the entire city and the rolling hills beyond.
