Chartres

Rising from a vast sandbank in the bay between Normandy and Brittany, Mont Saint-Michel looks like a vision from a medieval manuscript. This ‘Pyramid of the Sea’ is a gravity-defying cluster of monastic buildings stacked atop a rocky islet, crowned by a Gothic abbey that seems to pierce the heavens. For over a thousand years, pilgrims have braved the treacherous tides to reach its sanctuary, and today, it remains a place of profound spiritual and architectural significance. The walk up the narrow, winding Grande Rue is a journey through time, lined with 15th-century houses and shops. At the summit, the abbey offers a breathtaking panorama of the bay, where the fastest tides in Europe race in from the sea. It is a UNESCO World Heritage site that feels suspended between earth and sky.

A masterpiece of French High Gothic architecture, Chartres Cathedral dominates the skyline of the Beauce plain with its mismatched spires — one plain Romanesque, the other flamboyant Flamboyant — and its unparalleled collection of medieval stained glass. The nave, soaring 37 metres high, feels like a vessel of light, filtered through 176 windows that illustrate biblical stories in jewel tones of cobalt, ruby, and chartreuse. The famous Blue Virgin window (Notre-Dame de la Belle Verrière) and the labyrinth inlaid in the nave floor, still used for contemplative walks, are icons of medieval spirituality. The cathedral survived the French Revolution and both World Wars remarkably intact, preserving its sculpted portals, where countless stone figures teach theology in a ‘Bible of stone’.
