5 Interesting Facts About the Cathedral

1. Engineering feat: Brunelleschi’s dome is considered the first large dome built without scaffolding, a revolutionary achievement in the 15th century.
2. The largest brick dome: To this day, the cathedral’s dome remains the largest brick dome in the world.
3. Astronomical clock: On the inner wall of the cathedral, there is a unique clock by Paolo Uccello, which runs “backward” and marks time from sunset to sunrise.
4. 19th-century facade: The original Gothic facade was dismantled in the 16th century and remained unfinished until the 19th century, when the modern facade was created in a Neo-Gothic style.
5. Symbol of Florence: The cathedral is an integral part of the city skyline and symbolizes Florence’s rich cultural and historical heritage.

When building the dome, Brunelleschi used an innovative “herringbone” system that allowed the weight of the dome to be distributed evenly, preventing collapse. This technique was revived from ancient Roman architecture and was key to the project’s success.

Inside the cathedral, a meridian line was installed by astronomer Paolo dal Pozzo Toscanelli in 1475. Through a small hole in the dome, a ray of sunlight falls on the line on the floor, allowing the exact time of solstices and equinoxes to be determined.

Santa Maria del Fiore Cathedral is not just an architectural monument but a living museum, reflecting the history, art, and spirit of Florence. Visiting this cathedral will leave a lasting impression and bring you closer to the grandeur of the Renaissance era.
