Coat of Arms
The Certaldo onion
Mediaeval Certaldo's Coat of Arms (stemma) was a shield including a purple onion on a white background. This symbol can still be seen in a fresco on the wall of the Palazzo Pretorio. The town motto is a metaphoric encomium to the onion that can be loosely translated as “by nature I am both strong and sweet, and I please those at work and those at rest”.
The lowly onion was removed from the coat of arms in 1633, but reinstated 1867.
There are two varieties of Certaldo
the Statina, which is round in shape and purplish in color with succulent
flesh, and the bright red and pungent Vernina which is harvested from the end of August through the winter months.

Florence, reserving for himself only the tributes and alodial assets. But the definitive collapse for the Alberti Counts came soon after with the fall of

(1415). From 1400, the castle was enlarged to match its importance. It was surrounded with
stone walls and the imposing Palazzo Pretorio was constructed where in ancient times the residence of the Alberti Counts was
In 1479, Certaldo was sacked by the soldiers of the King of Naples
and Pope Sextus IV, allied
with Sienna, but
during the last Florentine republic and the Grand Duchy of Tuscany it grew again,
especially in the lower section called the "village" and in ancient times the Castle's market.
In 1784 Pietro Leopoldo suppressed the Vicariate, uniting it to that of
In consequence of the decline which then followed, the municipality managed to raise itself again only in the second half of the 1800s. During the second world war, between 1943 and 1944, it suffered losses and severe destruction. Postwar Certaldo rapidly recovered becoming
a busy agricultural and industrial centre.
