This compact half-day itinerary takes you through Les Andelys' remarkable medieval heritage in just 1.5 hours. Begin at the 13th-century Saint-Sauveur Church with its rare Greek cross design and one of France's oldest functioning organs. Then climb to the magnificent Château Gaillard, Richard the Lionheart's legendary fortress, offering spectacular views over the Seine valley. Important: Château Gaillard is closed Mondays and Tuesdays, and requires a steep 15-minute climb on rocky terrain - wear sturdy footwear. The castle is only open late March to early November. Total walking distance is approximately 700 meters between sites.
