were completed between 1692 and 1693. The first opening in the south wall of the city followed. François de Barral de Clermont, the uncle of the Tencin died in 1699 as the Dean of the Parliament of Grenoble. In 1751 the King established the territory of Allevard under his command under the name of the County of Barral as a perpetual lordship for Jean-Baptiste de Barral (1709–1785). Paulin de Barral 17 (1745–1822), his grandson, was the last lord of Allevard and of Jaligny in Bourbonnais who sold at a loss his castle and his factories in 1817 to A.B. Champel AB. The iron industry Allevard was an important centre for metallurgy and for the quality of its steel products until the early 20th century. There is a legend, created from the text of Suetonius and Polybius, which claims that Hannibal went to Allevard to manufacture his weapons. The history of Allevard is closely linked to the alpine steel industry. In 1450, Pierre and Arthur Boisson had a trip hammer in Allevard town which still existed in 1724. During a tour of the factory by special commissioners of the king in 1724 "it was determined to be the oldest of its kind in the kingdom" (E. Chabrand). Another Trip hammer at the same era was in operation in the village of Pinsot which is upstream on the Breda. A study of the remains indicated that the Allevard community had, between 1643 and 1727, a total of 76 works on the "Bredal" stream: 3 blast furnaces, 21 Trip hammers, 36 flour mills, 2 hemp beaters, 6 presses, 6 water-powered saws, 1 nail factory, and 1 fuller's earth plant. The steel industry was highly profitable because at the same time, the price per hundred kilos for the melting furnace - total production in Allevard was 54,255 kg - went from 4 livres 5 sols to 9 livres 10 sols. For many years Allevard remained an industrial site of great importance under as the blacksmith lords of the Barral family who constantly sought to innovate with the advice of the engineer Binelli and Sir Pierre Clement Grignon, collaborator in the Encyclopédie of Diderot. In 1785, the Barral establishments employed around 300 foundrymen, 300 miners, and 200 colliers to which should be added 100 mule-drivers. Of these 900 workers, only 420 were directly employed by the factory. Others worked independently particularly the miners and colliers.
