What major architectural achievement is Filippo Brunelleschi known for?

Filippo Brunelleschi is primarily celebrated for designing the dome of Florence Cathedral, also known as the Duomo. This monumental achievement is significant for several reasons. Firstly, it was an architectural breakthrough at the time of its construction in the early 15th century. The dome was the largest in the world and was constructed using innovative techniques, specifically a double-shell design, which allowed it to span an expansive width without the need for traditional wooden scaffolding.

Brunelleschi's mastery in combining form and function while employing advanced engineering principles played a crucial role in the emergence of Renaissance architecture. The success of the dome not only showcased his ingenuity but also influenced countless architects and builders following its completion.

In contrast, the other options relate to different historical figures and periods. The painting of the Sistine Chapel was accomplished by Michelangelo, while the Louvre Museum was initially built as a fortress in the late 12th century and later transformed into a royal palace, with its present form attributed to various architects over centuries.
