Forni della Signoria were big ovens used a long time ago in a special place called Florence, in Italy. They were built in the 1400s and were very important to the people who lived there at that time.
You see, in olden times, people used these ovens to bake bread, pizza, and other yummy things. But these ovens were not like the ones you have in your kitchen. They were much bigger, and they could heat up to very high temperatures.
People used the Forni della Signoria to bake bread for everyone in their town. They would make huge batches of dough, shape it into loaves, and then carefully place it in the hot ovens to cook.
These ovens were very important because they allowed people to make lots of bread at once, which was useful because there were always hungry mouths to feed.
The Forni della Signoria were also special because they belonged to the Signoria, which was a group of important people who ran the city. The ovens were a symbol of the Signoria's power and importance.
Today, you can still see the Forni della Signoria in Florence. They are like big, old-fashioned ovens made of red bricks, and they remind us of how people used to bake bread a long time ago.
