I cannot believe that I am on a Summer vacation in Florence, Italy with my family this very moment and we have just gazed upon this crown jewel of Italy several times.

This is an impressive structure, an awesome site any way you look at it. Been there in the 90's, climbed all the way up. Very fond memories.

If you can't visit it in real life, play Assassin's Creed 2. You'll get to climb up the dome from the inside. Oh it's an experience I'll never forget!

Very interersting! I was up there in 1983.

Sheesh, cheers to Brunelleschi's brilliance. It was inspiring to hear about - particularly at the end. He might've aimed to emulate and pay homage, but wound up surpassing. Love the inventiveness.

this is so beautiful! the view from the bell tower is breathtaking

Amazing video. Thank you for sharing. I've been reading up and writing about important 15th century people and Filippo Brunelleschi is in the top 10.

Irini. Fabulous tour once more. This was on my list for my next trip and even though I have enjoyed this I will still have the tour with you for real when this pandemic allows travel once again. Thank you. Stay safe

Interesting that you didn't really talk about the building as art so much as an engineering feat.
Either way I'm glad to find some good architecture content, hope there's more to come!

The Santa Maria del Fiore cathedral in Florence, Italy is the largest brick dome in the world. The dome was designed by Filippo Brunelleschi and was begun in 1296 and structurally completed in 1436. The technique used to build this masterpiece o has not been achieved. The explanations provided by speakers Beth Harris and Steven Zucker are very informative and detailed. Thanks.

In Gratitude to God the Creator for all he has given Us ". 🌏

Why was the dome's exterior never finished? Lack of money? War?

[gda]

i believe the keystone was an invention of the romans 300BCE

[jackbarnhill]

And, the man was neither an engineer or an architect. Incredible achievement.

You need to build a dome, but...
1) Gothic cathedral method of wooden framework is too expensive and nearly impossible
2) you don't have Roman concrete to do it like Pantheon
Brunelleschi - I have the answer

[sankadines]

I went to the top of the dome last week

It is not exactly correct to compare a dome with a vertical flat arch as the latter cannot protrude out and need support. Brunelleschi realised that the dome is a horizontal arch in the form of an ever decreasing circle and each layer of bricks at the circumference was in fact an ever decreasing complete arch wich is trying to fall upon itself towards the centre where he circumference goes into compression. What Brunelleschi saw was that the most important was to ensure that the horizontal circumference at each stage would not distort and in fact it had to e a circular beamand as it went higher the top circles were in compression while the lower ones slowly went into tension. Brunelleschi saw to it that the structure accounted for all that was required. Basically each pont on tha dome is held by what one could call the triangle of forces where one force is falling towards the centre and the other equal forces are circumferential from both sides of the point in question, every point is in fact held by a tripod! effect.

Are you two REALLY standing outside the Duomo?

my teacher is using this video we have to watch this in my 9'th grade class just sayin :P

Brunelleschi was a Double Pluss ++ good engineering genious in a bottle🍾
