Hérault (462), a maritime dep. of S. France fronting the Gulf of Lyons; in the N. are the Cévennes Mountains, but wide plains fringed on the sea border with large lagoons occupy the S.; the climate, except on the marshy coast, is dry and healthy; its former importance as a wine-growing district has greatly diminished, but olives and almonds are cultivated, sheep and silkworms bred; coal is the most important mineral; salt is obtained in large quantities from the salt marshes, and fishing is an important industry.
