The surname Semenza originates from Italy, specifically from the regions of Lombardy and Emilia-Romagna. It can be traced back to the late Middle Ages, around the 13th or 14th century. The name is derived from the Italian word "semenza," which means "seed" or "sowing." This suggests that the earliest bearers of this surname may have been farmers, gardeners, or individuals involved in agricultural activities.

One of the earliest recorded instances of the name Semenza can be found in the "Codice Diplomatico Longobardo," a collection of historical documents from the Lombard period in Italy, dating back to the 8th century.

During the Renaissance period, the Semenza family gained prominence in the city of Bologna, located in the Emilia-Romagna region. One of the most famous members of this family was Giovanni Battista Semenza, a renowned painter who lived from 1589 to 1668. His works can still be found in various churches and museums throughout Italy.

In the 18th century, Carlo Semenza, born in 1714 and died in 1788, was a prominent architect from Milan. He was responsible for designing several notable buildings in the city, including the Palazzo Litta and the Church of San Maurizio al Monastero Maggiore.
