The "Quercus Cerris" or Turkey Oak used to grow in great abundance on the banks of the river Belbo though their number has been thinned out over the years. This tree, which is depicted on the town's coat- of-arms and regularly mentioned in local archives, gave Cerretto Langhe its name. A fortified castle with four towers was built during the Middle Ages by the Cerretto family from Gorzegno. The castle and feudal lands passed into the hands of the Marquis of Susa in the 12th century. Bonifacio of Savona took control until 1142 when the Marquis of Ceva and Cortemilia took over. Then, as if to close an incomplete circle, the original owners, the Cerretto family became the last feudal lords. The main architectural feature of the town is the neogothic parish church and an ancient chapel, both in the centre. Like all towns in the Langa, Cerretto is located in an enchanting natural setting.
