This carefully curated itinerary takes you through Gisors' most significant medieval landmarks, all within comfortable walking distance. Begin your morning at the magnificent 11th-century Château de Gisors, one of Europe's most impressive Norman fortresses perched atop a 30-meter artificial mound, where you'll explore the octagonal keep, underground cellars, and the mysterious Prisoner's Tower with its Templar graffiti. Continue to the cathedral-sized Church of Saint-Gervais-Saint-Protais, a Gothic masterpiece showcasing 400 years of architectural evolution from Romanesque to Renaissance, featuring stunning 16th-century stained glass and the remarkable Tree of Jesse sculpture. Conclude your walk at the charming 15th-century Washhouse on the banks of the Epte River, a protected monument that served as the town's social hub for nearly 500 years. Important: The Château is closed on Tuesdays and requires a guided tour (€9, book in advance). The church and washhouse offer free entry. All three sites are within a 15-minute walk of each other, making this an easy and relaxed day of discovery in historic Normandy.
