Medieval boom time
Following on from a probable Roman foundation, the upper town, or Royal City, began flourishing during the 6th century with the construction of a priory dedicated to St. Ursus. Circa 900 and lasting more than three centuries a succession of Counts of Anjou, who later ascended to the throne of England, transformed Loches into a formidable stronghold.
Fulk III, known as Fulk the Black, built the keep during the 11th century. During the 13th century the lower town developed as a result of the trade route linking Paris to Northern Spain. The Royal Residence was also built during this period.
To protect its population, the town built several levels of defensive systems, many of which still remain today. Three towering medieval gateways still welcome visitors: Porte Picois, Porte des Cordeliers and Porte Royale, which Joan of Arc passed under on her way to meet Charles VII.
