From Amfreville the road winds steeply down to the charming valley of the Andelle, and crosses the river at the village of St. Nicholas-de-Pont-St. Pierre, where there is a fine fifteenth-century château, approached by an avenue of evergreen trees. There is an imposing façade flanked by two towers, and close by are the ruins of an older castle. After a steep, winding ascent through the forest of Longboël the plateau of Caux is reached, the River Andelle dividing it from that of Vexin. At Boos the _route nationale_ is joined, and one may stop to see the remarkable ruins of a thirteenth-century manor-house of the Abbesses of St. Armand de Rouen. The beautiful octagonal pigeon-house of the sixteenth century is decorated with inlaid tiles. Just before descending the steep hill down to Rouen, from whence there is a remarkable panorama of the city, the village of Blosseville Bonsecours is passed through. An important Benedictine abbey was founded there in 1030. It was fortified in the fourteenth century, but in 1597, after the wars of the League, it was destroyed at the demand of the people of Rouen, who had always been apprehensive that the cannons would be turned upon them. * * * * * The routes from Rouen to Havre, Dieppe, Boulogne and Calais, are described in Section I.
