Where to find it: Palazzo Antinori; chiesa di San Gaetano - both on via de' Tornabuoni.
The Antinori came to Florence in the 1300s and were soon involved in the silk trade. A bit later on, the family became involved in viticulture, and established what is today the third oldest continually-producing vineyard in the world. A branch of the family also exists in Naples. Both branches were ennobled; the Florentine branch with the title of Marquis and the Neopolitan branch with the title of Duke.
