Blois (blwɑː ; blwa) is a commune and the capital city of Loir-et-Cher department, in Centre-Val de Loire, France, on the banks of the lower Loire river between Orléans and Tours.
With 45,898 inhabitants by 2019, Blois is the most populated city of the department, and the 4th of the region.
Historically, the city was the capital of the County of Blois, created on 832 until its integration into the Royal domain in 1498, when Count Louis II of Orléans became King Louis XII of France. During the Renaissance, Blois was the official residence of the King of France.
Since 2013, excavations have been conducted by French National Institute of Preventive Archaeological Research (INRAP in French) in Vienne where they found evidence of "one or several camps of late Prehistory hunter-gatherers, who were also fishermen since fishing traps were found there.. [...] They were ancestors of the famous Neolithic farmer-herders, who were present in current France around 6,000 BCE [i.e.: 8,000 years ago]."
A major urban development begun in 1959 uncovered the remains of a late Gallic settlement and an urban centre from the Gallo-Roman period. At that time, the town was located on the road linking Chartres to Bourges. In the network of cities of the Carnutes people, Blois was a secondary settlement. Excavations carried out on the right bank between 2001 and 2016 and on the left bank in 2013-2014 revealed the presence of a largely developed town on the right bank and an occupation on the left bank during the Gallic and Gallo-Roman periods. The Loire river has undoubtedly always been a major axis route, although no traces of a port have been uncovered. However, there are remains of former bridges linking the two banks.
Though of ancient origin, Blois is first distinctly mentioned by Gregory of Tours in the 6th century, and the city gained some notability in the 9th century, when it became the seat of a powerful countship known as Blesum castrum by the counts of Blois.
Blois was first organised around a county, which was recreated in 956 by Count Theobald I of Blois, also known as The Trickster.
