During the Middle Ages in Western Europe gradually lost the ability to build large domes, mainly by the technical difficulties posed by the construction scaffolding ever higher and resilient, as a way of supporting the dome under construction until its closing by putting up static key.

However, it continued to build domes of small and medium-size, especially in the most prestigious buildings such as chapels and cathedrals palate. During the time of the crusades is rebuilt the Basilica of the Holy Sepulcher in Jerusalem, destroyed in the war with the Muslims, through a dome adintelada empirically. The influence of the center of Christianity led to his playing in several cities in Europe. One of the oldest preserved in the Baptistery of Pisa, dating from the eleventh century.
The important urban development occurred after the millennium, it allows the rapid dissemination of this technique, and thus re-constructed buildings with domed cupola. From this moment, the main buildings with domed basilica was built on ships, called "dome".

Spontaneously "dome" to become synonymous with leadership, with the meaning of which is the term used in French and English.
In a competition to create increasingly large buildings, tall and majestic, the construction of the cathedral at Florence Santa Maria del Fiore, planned from the beginning of the crown by a large dome apse.
When the architect Francesco Talenti large in the fourteenth century the floor of the cathedral, no one knew how to construct the project was that the dome biggest so far. Filippo Brunelleschi was the first half of the fifteenth century who, after studying Roman architecture design a solution that avoided the use of internal scaffolding.
The solution was to build two domes, one inside the other, which was sustained through a partnership structure reinforcements in sight.
Brunelleschi's solution was the direct inspiration of Michelangelo when he had to design a dome for the project's most important late Renaissance, St. Peter's Basilica in the Vatican. I think a circular majestic dome that dominates the city of Rome, and symbolic throughout Christendom. The robust ribs discharge the weight of the structure allowing a better control on the shape and volume of both the outer shell and the intrados. The extrados is slightly enhanced, with the hyperbolic arriostramientos vaguely showing lines upstream of the building.
Curious cupola of the sixteenth century is the dome that serves as a flat floor in the church choir of the Monastery of the Escorial, which is equal to the construction of a dome, with voussoirs, but cross-sectional plane, a display designed by John tecnico Herrera.
