[Illustration: TOWN PLAN NO. 2--DIEPPE. _Walker & Boutall sc._] BOULOGNE TO ROUEN (109½ miles--176 kilometres) This road is through the little town of Samer, where there is an interesting fifteenth-century church and the ruins of the Abbey of St. Wulmer. Soon afterwards there is a steep hill. Montreuil-sur-Mer has a Palais de Justice, which was formerly part of a Carmelite convent, and the college and École d’Infanterie occupy the buildings of the Abbey of Ste. Austreberthe. The chapel of the Gothic Hôtel Dieu has a curious altar-screen, and the very interesting Church of St. Saulve dates from the twelfth century. The view seawards down the Canche from the citadel, which is surrounded by towers and walls of the Middle Ages, is remarkably fine. On the road to Abbeville there is a steep ascent at Nampont St. Martin, and a steep descent to Bernay-en-Ponthieu. The forest of Crécy lies to the left of the road, and on the farther side of it is the medieval battlefield, where the English army, under Edward III., crushingly defeated the French in 1346. Abbeville is an interesting old town, still possessing some very good specimens of its domestic architecture of the thirteenth, fifteenth, and sixteenth centuries. The best are the Maison François I., with richly carved woodwork, at 29, Rue de la Tannerie; No. 2 in the same street (sixteenth century); 7, Rue du Pont de Boulogne; 3 and 5, Rue de l’Hôtel de Ville; 41, Rue de la Boucherie; and, besides these, several others will be noticed in a walk through the town. There are also some good town houses, or _hôtels_, in the Rue St. Gilles. The Church of St. Vulfran belongs to the sixteenth and seventeenth centuries, and is remarkable for its fine restored façade, with beautifully sculptured doorways. The interior is not remarkable, except for two curved altar-screens. The Hôtel de Ville has a bell-tower dating from the beginning of the thirteenth century, and the library in the Jardin Public d’Emonville contains a Gospel which belonged to Charlemagne. Neufchâtel-en-Bray is famous for its cheeses, and is the chief town of the district, which has been called ‘the dairy of Paris.’ It was at one time called Driencourt, the name having been altered when a new castle was built by Henri Beauclerc. The Church of Notre Dame, of various periods from the twelfth century, has a sixteenth-century tower. A passage from the Grand Rue leads to the Maison des Templiers, a most picturesque timber-framed building, with much carved woodwork. From Neufchâtel to above the River Arques the road climbs, dropping steeply down to that river at St. Martin Omonville. After leaving the valley the road is comparatively level to Rouen.
