Most people would recognise this as the dome designed by Brunelleschi for the Cathedral of Santa Maria del Fiore in Florence. Most people would also simply call this cathedral the Duomo.
I had read about a 1:5 scale model of the dome that had been built by Professor Massimo Ricci in Florence, and really wanted to have look at this. I knew it was in Anconella Park, and after being in Florence for a while, I felt confident that I could find it. I walked along the Arno River, heading upstream, for about an hour. After asking quite a few people about the exact location of the model, I struck a nice gentleman walking his equally nice dog. He kindly retraced his steps to lead me to the site, saying he had never seen it himself.
Here is my first sighting of the model.
And, here are some closer views. Unfortunately, there’s no way to get inside the structure, so we can’t see what the interior brick-work looks like. Still, it was a little thrill to achieve success in finding it, and to see how Brunelleschi (and the Professor) had accomplished this architectural/engineering feat.
