100 years history

In its century-old history, Olivari has always sought out the maximum in quality, relying on the creativity of the best designers and architects. The Olivari family has handed down its attention to details, the search for innovation, and mainly a passion for its work, from generation to generation.

In the Beginning

Battista Olivari founds the company in 1911 in Borgomanero, in the province of Novara; its plants are still there and its handles are entirely manufactured there. In 1926, Battista is succeeded by his wife Antonietta Ramelli, one of the few women directing a company at the time. In the 1930s, the first collaboration with architects begins with Marcello Piacentini and Gio Ponti, two of the important Italian architects of the area.
