Filippo Brunelleschi in the context of "Architectural"

Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes from Latin architectura; from Ancient Greek ἀρχιτέκτων (arkhitéktōn) 'architect'; from ἀρχι- (arkhi-) 'chief' and τέκτων (téktōn) 'creator'. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.

The practice, which began in the prehistoric era, has been used as a way of expressing culture by civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times. The earliest surviving text on architectural theories is the 1st century BC treatise De architectura by the Roman architect Vitruvius, according to whom a good building embodies firmitas, utilitas, and venustas (durability, utility, and beauty). Centuries later, Leon Battista Alberti developed his ideas further, seeing beauty as an objective quality of buildings to be found in their proportions. In the 19th century, Louis Sullivan declared that "form follows function". "Function" began to replace the classical "utility" and was understood to include not only practical but also aesthetic, psychological, and cultural dimensions. The idea of sustainable architecture was introduced in the late 20th century.

Florence Cathedral (Italian: Duomo di Firenze), formally the Cathedral of Saint Mary of the Flower (Italian: Cattedrale di Santa Maria del Fiore [katteˈdraːle di ˈsanta maˈriːa del ˈfjoːre]), is the cathedral of the Catholic Archdiocese of Florence in Florence, Italy. Commenced in 1296 in the Gothic style to a design of Arnolfo di Cambio and completed by 1436 with a dome engineered by Filippo Brunelleschi, the basilica's exterior is faced with polychrome marble panels in various shades of green and pink, alternated by white, and features an elaborate 19th-century Gothic Revival western façade by Emilio De Fabris.

The cathedral complex, in Piazza del Duomo, includes the Florence Baptistery and Giotto's Campanile. These three buildings are part of the UNESCO World Heritage Site covering the historic centre of Florence and are a major tourist attraction of Tuscany. The basilica is one of world's largest churches and its dome is still the largest masonry dome ever constructed. The cathedral is the mother church and seat of the Archdiocese of Florence, whose archbishop is Gherardo Gambelli.

Renaissance architecture is the European architecture of the period between the early 15th and early 16th centuries in different regions, demonstrating a conscious revival and development of certain elements of ancient Greek and Roman thought and material culture. Stylistically, Renaissance architecture followed Gothic architecture and was succeeded by Baroque architecture and neoclassical architecture.

Developed first in Florence, with Filippo Brunelleschi as one of its innovators, the Renaissance style quickly spread to other Italian cities. The style was carried to other parts of Europe at different dates and with varying degrees of impact. It began in Florence in the early 15th century and reflected a revival of classical Greek and Roman principles such as symmetry, proportion, and geometry. This movement was supported by wealthy patrons, including the Medici family and the Catholic Church, who commissioned works to display both religious devotion and political power. Architects such as Filippo Brunelleschi, Leon Battista Alberti, and later Andrea Palladio revolutionized urban landscapes with domes, columns, and harmonious facades. While Renaissance architecture flourished most in Italy, its influence spread across Europe reaching France, Spain, and the Low Countries adapting to local traditions. Public buildings, churches, and palaces became symbols of civic pride and imperial strength, linking humanism with empire-building.

The Renaissance in Rome occupied a period from the mid-15th to the mid-16th centuries, a period which spawned such masters as Michelangelo and Raphael, who left an indelible mark on Western figurative art. The city had been a magnet for artists wishing to study its classical ruins since the early 15th century. A revived interest in the Classics brought about the first archaeological study of Roman remains by the architect Filippo Brunelleschi and the sculptor Donatello, both Florentines. This inspired a corresponding classicism in painting and sculpture, which manifested itself in the paintings of Masaccio and Uccello. Pisanello and his assistants also frequently took inspiration from ancient remains, but their approach was essentially cataloguing, acquiring a repertoire of models to be exploited later.

In the year 1420, Pope Martin V moved the papal seat back to Rome, ending its long Avignon Papacy or "Babylonian captivity", and the Papal Schism, when several "popes" simultaneously claimed the office. He at once set to work, establishing order and restoring the dilapidated churches, palaces, bridges, and other public structures. For this reconstruction he engaged some famous masters of the Tuscan school, and thus laid the foundation for the Roman Renaissance.

A cathedral is a church that contains the cathedra (Greek for 'seat') of a bishop, thus serving as the central church of a diocese, conference, or episcopate. Churches with the function of "cathedral" are usually specific to those Christian denominations with an episcopal hierarchy, such as the Catholic, Eastern Orthodox, Anglican, and some Lutheran churches. Church buildings embodying the functions of a cathedral first appeared in Italy, Gaul, Spain, and North Africa in the 4th century, but cathedrals did not become universal within the Western Catholic Church until the 12th century, by which time they had developed architectural forms, institutional structures, and legal identities distinct from parish churches, monastic churches, and episcopal residences. The cathedral is more important in the hierarchy than the church because it is from the cathedral that the bishop governs the area under his or her administrative authority.

Following the Protestant Reformation, the Christian church in several parts of Western Europe, such as Scotland, the Netherlands, certain Swiss Cantons and parts of Germany, adopted a presbyterian polity that did away with bishops altogether. Where ancient cathedral buildings in these lands are still in use for congregational worship, they generally retain the title and dignity of "cathedral", maintaining and developing distinct cathedral functions, but void of hierarchical supremacy. From the 16th century onwards, but especially since the 19th century, churches originating in Western Europe have undertaken vigorous programmes of missionary activity, leading to the founding of large numbers of new dioceses with associated cathedral establishments of varying forms in Asia, Africa, Australasia, Oceania and the Americas. In addition, both the Catholic Church and Orthodox churches have formed new dioceses within formerly Protestant lands for converts and migrant co-religionists. Consequently, it is not uncommon to find Christians in a single city being served by three or more cathedrals of differing denominations. For example, London is home to the Anglican St Paul’s Cathedral, the Catholic Westminster Cathedral & St George's Cathedral, and several Eastern Orthodox cathedrals serving different national communities.[1]

The historic centre of Florence is part of quartiere 1 of the Italian city of Florence. This quarter was named a World Heritage Site by UNESCO in 1982.

Built on the site of an Etruscan settlement, Florence, the symbol of the Renaissance, rose to economic and cultural pre-eminence under the Medici in the 15th and 16th centuries. Its 600 years of extraordinary artistic activity can be seen above all in the 13th-century cathedral (Santa Maria del Fiore), the Church of Santa Croce, the Uffizi and the Pitti Palace, the work of great masters such as Giotto, Filippo Brunelleschi, Sandro Botticelli and Michelangelo.
