The oldest evidence of a settlement in the area is a reasonable well preserved section of a
Roman road. Around 640 what became the
Moutier-Grandval Abbey was established outside the village of Grandval. The town of
Moutier then developed around the Abbey complex. Grandval is first mentioned around 900 as
Grandemvallem. The village chapel of St. Martin was first mentioned in 962. By the 14th century it had become the
parish church for Grandval
parish, which included most of the communities in the Grand Val/Moutier valley. In 1531 the village, its church and the parish converted to the new faith of the
Protestant Reformation. Beginning in 1663 the church was almost constantly under construction for several centuries. Major reconstruction projects happened in 1701-06 and 1927. For most of its history, the village of Grandval was owned by the Abbey. After the
1797 French victory and the
Treaty of Campo Formio, Grandval became part of the French
Département of
Mont-Terrible. Three years later, in 1800 it became part of the Département of
Haut-Rhin. After
Napoleon's defeat and the
Congress of Vienna, Grandval was assigned to the Canton of Bern in 1815. Until about 1900, the local economy was still dominated by agriculture with a few cottage industries that manufactured pottery, watch parts and
arquebuses. This began to change with the growth of the machinery manufacturing industry in nearby
Moutier and the construction of the
Solothurn-Moutier railroad in 1904-08. A number of industrial factories settled in Crémines and remained. Today over half of the working population is in the industrial sector. ==Geography==
