How Was the World's Biggest Dome Built? - Florence Cathedral

Florence Cathedral remained without a dome for more than a century, for nobody was capable of building it, until Filippo Brunelleschi presented a promising solution in 1418, but how did he do it? Join me and discover the secrets of the construction that started the Renaissance.

What is your favorite Renaissance building?

[@Joshua_Knowles_]

the piazza san marco in venice or florence cathedral 👍👍

[@Nicods]

Brabante's Tempietto di San Pietro in Montorio in Roma.

[@29trent]

The Pazzi Chapel at Sta Croce or the Vasari Corridor

[@Rays_Bad_Decisions]

The largest dome is Hagia Sofia in Istanbul until modern stadiums were built

[@msrjorge1805]

Wow! Magnificent dome and the video with great explanations

[@johnenglish929]

He was way ahead of his time in terms of concern for the safety of his workers. From memory, only two people dies in the building of the Duomo - sad, but incredibly low compared with the standards at the time. An incredible man. A true genius.

[@Davidson015]

Given the scale and difficulty of the construction two deaths is a low number even compared to today's standards. Source: I have a construction company.

[@FlorentPlacide]

I went to Firenze when I was young and I was awestruck by the mystery and the magnificence of this city. Most of it is so well-preserved you can feel the centuries and the thousands of lives that spent here just by walking the streets. I long to go back and to wander and wonder in the former Republic. Thank you for this video and these amazing shots.

Brunelleschi was such a genius! Amazing video, as always! ❤️

[@ManuelBravo]

He was indeed! Thanks for your comment Ju!

[@argiberico]

I wonder who FLorentines love more, Brunelleschi o Batistuta 😅

[@BauAuslese]

One genius is not enough for a task of this magnitude. You need a crowd of experienced workers who are very well organized. In that aspect the dome is a testimony to cooperation, discipline and maybe to religious faith who led them to take the risk.

[@AndyFromBeaverton]

@@ManuelBravo He was the original Renaissance man before Leonardo da Vinci took his crown.

[@danielefabbro822]

Brunelleschi and the Bernini was the two most prolific and illustrious artists of their time.

[@Bosse_C]

people these days copy anything

[@JanVP1]

9:58 That's what I thought too: "When you climb to the top of the campanile"

[@1fandik]

Being on top of the dome was the most amazing experience ever. And not to mention climbing and seeing all the skeleton up close. What human hands can do with minimal tools is astounding. È capolavoro costruito per generazioni

[@michaelallen5505]

Also amazing was the hoist to lift the thousands of tons of material. It was driven by oxen turning in a circle. It used a special feature for lowering material without the oxen changing direction. Yes, he also invented the reverse gear!

[@maily8388]

I always amazed how the Roman could hoist the building materials up to the hills since most of Italy cities are up hills. There’s only 20% flat land in Italy. Since walking alone uphills we were huffing buffing. On top of that, how could the Roman pumped water uphills and how public fountains water created pressures to pump the water for Romanians to use?

[@lupepedraza8497]

I climbed the Dome. What a marvelous construction!

[@solecipollari]

Lasy month I was visiting Firenze and Italy for the first time in my life (really hope not the only one) and spent my birthday evening climbing the campanile and I was up there and I cried, listening to someone playing Allelujah in the street. Now I watch your video and I'm crying again. That places and experiences are uniques and incredibles. Thank you for this wonderful video! Greets from Córdoba, Argentina. 🙂🙃

[@kesharisuthar3268]

Myself and wife visited FLORENCE in September 2008. Not only this super dome, entire city is like a large sized museum. Stunning sculptures, breathtaking & beautiful buildings, classic churches, finest floor designs, wonderful wall paintings ; these all combine to make FLORENCE the best heritage city. ❤❤❤❤❤❤

[@starcrib]

Again: your skills at storytelling and production value is absolutely engaging, historical, and factual. Thanks for this. 🌍🌎🌏

[@roberttodd8889]

The amazing thing about the elevator/lift for materials was that Brunelleschi invented a transmission that allowed both raising and lowering of the lift without reversing the horses. They could continue to move the same direction in a circle and the position of the transmission would determine whether the lift was raising or lowering.

[@lancer525]

Oxen, not horses.

[@marcoriglione6819]

i’m from florence, born here, this is a awesome video, thank you ❤

[@wadeunderhile7977]

Was there in the late 70s absolutely beautiful and amazing. The old bridge that crosses the river is amazing, a beautiful city

[@pepumarius2006]

when visiting Florence this summer, I wondered what would a construction work genius like Brunelleschi achieve if he lived in modern times? The visit to the top of the dome was a bit... difficult, but oh boy was it worth the effort. All the way up you can marvel at his genius as you can observe details in the construction. Loved each and every moment of it. Great video Manuel!

[@danielefabbro822]

Just go google Renzo Piano.

[@Ozymandi_as]

First time I've seen one of your videos, just appeared in my feed, and reminded me of my first trip to Florence as a student, many years ago. I dimly remembered that double skin construction, and the stairway that wound through it. And the view from the cupola over those terracotta rooftops. Your explanation of Brunelleschi's ingenuity, and the lessons he'd learnt from classical Rome, was really good. Amazing how intuitive he was, before the maths and physics of calculus and catenaries was available to help him. It seems that like many others, he must have been inspired by Florence. The art, the architecture, the literature and the ideas that came from men who found their way to that city illuminated all of Europe, after centuries under darkness. It's fantastic that so much of what was laid out, built and made 6 centuries ago has survived intact for us to admire and learn from today.

[@kenjd57]

Thanks for the in-depth history of the dome in Florence.

[@user-mi8ig6yx6x]

Спасибо, Мануэль! Отличный рассказ о том событии, которое называется: "Постройка купола собора во Флоренции без лесов". Событие это, как вы видите, уникально настолько, что ему не перестают сильно удивляться до сих пор.

[@stephenmccallion3407]

Fantastic documentary, and Mr. Bravo is an excellent teacher!

[@myvirtualpresencefyi]

Thank you so much. I visited the dome in 1986. In the 90s I studied Architecture so I'd have said that I was quite knowledgeable about this subject but your video & explanation is on another level. Professionally: thank you. Emotionally: thank you.

[@hugodesrosiers-plaisance3156]

As a journeyman woodworker, the sheer class and ingenuity of some solutions people came up with in those days is absolutely inspiring. I recently subscribed to your channel and I'm loving every video so far. Thanks for posting!

[@mcswordfish]

Fantastic and interesting video. I've been to Florence twice, climbed the Duomo once, and it remains one of the most spectacular buildings I've ever visited.

[@bwhog]

Brilliant! Absolutely brilliant design and execution! What a fascinating look at the structure Brunelleschi was inspired to build and what a tremendous marvel of his day. I'm always fascinated by what people were capable of in the days before highly refined mathematics and structural engineering, not to mention machines to make the work faster and easier if not merely possible in the first place. Magnificent!

[@anupamroy7935]

Excellent work.

[@prototropo]

Thank you, Manuel! Your videos are so beautifully narrated, with such a deep command of architecture theory.

[@pep_4_climate]

Say bravo to you Manuel! That's a great story that combines Architecture, Solid Mechanics, Arts, and History! Wish you the best! :)

[@HamelinSong]

Fun facts: It took about 140 years to finish this cathedral. The bronze orb fell twice. The thobolate of the dome is ornate only on one of the 8 sides, the rest did not fell, Baccio d'Agnolo created the balcony, but Michelangelo said it was ugly so, offended, he never finished it. Yes, 727 years later, still not finished (take that Sagrada familia!)

[@3399italiano]

Absolutely fantastic video, Manuel ! Thank you so much. Very clear, very detailed and yet succint explanation of how one of Mankind’s masterpieces was built. An absolutely MUST WATCH for anyone planning to visit but also for those who alredy visited !

[@tc3884]

6:54 when I visited florence, I didn’t read up on the dome before I saw it for the first time. I marvelled at its beauty and the fact that the structures that keep the dome together are hidden under beautiful, colourful marble art. When I saw the part bare wall below the dome I thought I’m lucky to see it because this must be due to restoration works on the marble. How wrong I was ! It’s amazing to learn that they made the choice to leave this part of the wall uncovered. It proves that they knew, people would wanna see a part of structure below the beautiful marble cover. So well thought out !

[@kacperwoch4368]

Honestly I doubt this story, Michelangelo did not own the cathedral to make such decision, far more likely they run out of money and left it unfinished. The facade also remained unfinished for centuries until it was finished.

[@antoniomonter0]

Manuel, tus videos son una verdadera inspiración, de verdad te admiro muchísimo. Sigue con ese excelente trabajo 🧠

[@hazhoner5727]

The genius of Italians spread among all human fields

[@SJR_Media_Group]

Thank you for an amazing video... Even today this would be considered a very technical build. The fact he did it hundreds of years ago is beyond amazing. The Romans thought they had mastered gravity and structures. Brunelleschi definitely exceeded even the best Roman Architecture. Now we know who, where, why, and how it was done.

[@RichieTyndall]

Oh, how I would love to visit Florence and see this wonder for myself. I remember watching a tv series on its construction. Thanks a million for this video.

[@brunerguy1]

This is the best description of the Dome I've ever seen! Thanks!

[@henrylares9269]

Excellent documentary… and that comes from an Architectural History professor. Keep up the good work.

[@amalkardaly1652]

I cant imagone how proud he must have been to see it finally finished!

[@danielsantos3124]

Nice video! You might be interested in knowing that after a recent restauration, the romanic cupola of the Zamora Cathedral in Spain, finished in 1174, it was found to be the first double casquet cupola so far in history of architecture. It's a very nice cupola of bizantinian influence.

A massive undertaking for it's time, and brilliantly executed.

[@drew6194]

It's much more of a massive undertaking for this time. Nothing we build now can compare to this in any manner.

[@andreadanaegomez5396]

Me encantó! Súper bien explicado y cuando fui a Florencia me había quedado con la duda! Muchas gracias

[@jeffbrinkerhoff5121]

Before Brunelleschi secured the commission there was a younger rival, Bartolomeo Boromini, also soliciting for the job. I believe the story is told in the book you mention, "Brunelleschi's Dome". Very nice video.

[@robertopinzani6774]

Bartolomeo Boromini? The concorrent of Filippo Lapi was Lorenzo Ghiberti ,initially they lead the built of the dome together , Bartolomeo Borromini never existed, maybe you refer to Francesco Borromini but he lived two centuries after Filippo Lapi ( Brunelleschi or Filippo di Brunellesco Lapi, Ser Pippo for us the florentines) Or maybe you refer to Michelozzo di Bartolomeo learner under Ghiberti , who lived and operated in Florence in middle 1400 being the architet of Cosimo il vecchio. Study bro.... you and fives who puts likes on your comment.

I remember climbing up to to top of the dome when I was in Florence four years ago. I use climbing because that was not an easy assent. I nearly had a claustrophobia attack on those tight spiral staircases on the way up. The view was beyond worth it
