Architecture

Although Arnolfo's architectural activity is now less clearly defined than his work as a sculptor, in Vasari's view his reputation was based on his architecture. The only documentary evidence of Arnolfo's work as an architect relates to the rebuilding of Florence Cathedral, plans for which were being made from 1294; the foundation-stone was consecrated in 1296. Construction ceased after Arnolfo's death and was resumed only after 1355; the cathedral was not finally completed until the 15th century.

Vasari attributed a number of other important buildings, renovations and urban development projects in Florence and its territory to Arnolfo: the third city wall; the Loggia of Orsanmichele, the Loggia dei Lanzi, the Palazzo Vecchio and the Piazza della Signoria; the choir of the Badia with its flanking chapels; the Franciscan church of Santa Croce and the older cloisters of the monastery attached to it; the marble facing on the Baptistery; and the castles of San Giovanni and Castelfranco in the Arno Valley. Only the Badia and Santa Croce are now seriously regarded as Arnolfo's work.
