I've seen many of the great churches of France: Chartres, Notre Dame, Poitiers, Toulouse, St. Bertrand-de-Comminges, Lisieux, Limoges, Albi, Vézelay, Avignon, many others. In my opinion, this one in Bourges is the most awe-inspiring! (It's not really this yellow. This image was scanned from an enhanced photo on a postcard.)
