The castle of the counts of Perche stands on a hill overlooking the French town of Nogent-le-Rotrou, in the central Eure-et-Loir department. This thousand-year-old fortress, testament to a wealth of local history, is now a museum. Through nearly 400 objects, it takes visitors on a journey through time, from the Middle Ages to the French Revolution. FRANCE 24 takes you on a tour.
