Filippo Brunelleschi

Born in 1377 in Florence, Filippo Brunelleschi, a skilled goldsmith turned architect, left an indelible mark on Renaissance art. Best known for designing the iconic dome of the Cathedral of Santa Maria del Fiore, he revolutionized architecture with innovative machines for construction. Lead architect of notable structures like the Church of Santo Spirito and the Ospedale degli Innocenti, Brunelleschi's legacy extends beyond his birthplace.

Structure of Duomo Florence

Materials used

  • The exterior of the Cathedral of Santa Maria del Fiore building is made primarily of marble sourced from the nearby quarries of Carrara, Massa, and Prato. 
  • The pink, green, and white marble used in the exterior facade were chosen for their beauty and ability to withstand the weather. The base of the building is made of sandstone, while the ribbed vaults and arches are made of brick.
  • The interior of the Duomo is also made of different types of marble, including white Carrara, green Prato, and red Siena marble. The intricate designs and sculptures that adorn the interior are made of stone, and the floors are made of colored marble in geometric patterns.

Innovative techniques

  • Brunelleschi employed groundbreaking techniques for Duomo's cupola. For example, he used two layers of bricks instead of a wooden frame to support the dome.
  • The inner and outer shells were connected by a self-supporting structure, which allowed for the dome to be very large without needing additional support from flying buttresses, which are typically used in Gothic architecture.
  • Brunelleschi also used a special brick-laying technique called the herringbone pattern, which helped distribute the weight of the dome more evenly.
  • To further reinforce the structure, he used iron chains that were embedded in the masonry. These chains added extra strength and durability to the dome, allowing it to withstand the test of time.

Stages of construction of Duomo Florence

Early 14th Century: The ambitious project to build the Cathedral of Santa Maria del Fiore began in 1296, with the initial designs by Arnolfo di Cambio. However, progress was slow, and the structure faced several interruptions.

1401 - Brunelleschi's Ingenious Design: Facing the challenge of constructing a massive dome without a temporary wooden support structure, a competition was held in 1401. Filippo Brunelleschi's innovative double-shell dome design won, marking a pivotal moment in Renaissance architecture.

1402 - Beginning of Brunelleschi's Work: Brunelleschi started working on the dome in 1420, utilizing groundbreaking techniques. He employed a herringbone brick-laying pattern, embedded iron chains for reinforcement, and created a self-supporting structure with inner and outer shells.

1436 - Completion of the Dome: Brunelleschi's ingenious engineering led to the completion of the dome in 1436. The structure, known for its immense size and architectural brilliance, became a symbol of Renaissance achievement.

19th Century Additions: In the 19th century, Emilio De Fabris added a Gothic Revival facade to the western side, enhancing the cathedral's external aesthetics.
