1911 Encyclopædia Britannica/Lavagna

LAVAGNA, a seaport of Liguria, Italy, in the province of Genoa, from which it is 251/2 m. S.E. by rail. Pop. (1901) 7005. It has a small shipbuilding trade, and exports great quantities of slate (lavagna, taking its name from the town). It also has a large cotton-mill. It was the seat of the Fieschi family, independent counts, who, at the end of the 12th century, were obliged to recognize the supremacy of Genoa. Sinibaldo Fieschi became Pope Innocent IV. (1243–1254), and Hadrian V. (1276) was also a Fieschi.
