What year was the Dome of Florence Cathedral completed?

The Dome of Florence Cathedral, also known as the Duomo, was completed in 1436, and construction began under the direction of Filippo Brunelleschi in 1420. The year 1418 is significant because it marks the time when Brunelleschi was commissioned to design the dome and began his innovative engineering work, ultimately leading to its completion in the following years. This engineering feat represented a major advancement in architecture and became a defining symbol of Florence.

The other years listed do not align with the key events in the history of the dome. Hence, 1418 is associated with the start of the dome’s construction, effectively making it the most relevant year in the context of its completion.
