Begin your medieval adventure in Provins by climbing the Tour César, the iconic 12th-century keep with walls three meters thick, for commanding views over the remarkably preserved ramparts and countryside that once hosted the famous international Champagne fairs where merchants from across Europe traded goods worth fortunes in silk, spices, precious metals, and rare wines that connected East and West in medieval commerce. Walk along the medieval city walls, among the best-preserved in Europe with their original battlements, defensive towers, and gates still intact after 800 years of weather, wars, and the passage of time that have failed to diminish their impressive grandeur. Descend into the mysterious underground galleries (souterrains) that honeycomb the city beneath—vast networks of vaulted cellars that served merchants during the Champagne fairs for storing precious goods and conducting business away from prying eyes, harsh weather, and potential thieves who threatened medieval commerce. Visit the impressive Tithe Barn with its remarkable wooden framework and learn how medieval merchants conducted international business in this commercial crossroads that rivaled Paris in wealth and importance during the 12th and 13th centuries when Provins was one of Europe's richest and most influential cities. Time your visit for one of the spectacular medieval shows—watch armored knights battle on horseback during 'The Legend of the Knights' with authentic weapons and combat techniques, or witness magnificent birds of prey soar during the falconry demonstration showcasing hunting methods used by medieval nobility and the deep connection between humans and nature in medieval culture. End your day exploring the atmospheric medieval streets lined with stone houses and visiting Saint-Quiriace Collegiate Church with its unique mix of Romanesque and Gothic architectural styles spanning centuries of construction and the changing tastes of medieval builders.
