The Forest of St. Germain-en-Laye, through which the route goes towards Pontoise, occupies practically the whole of the area enclosed by the third loop of the Seine below Paris, and was formerly part of the immense forest of Laye, one of those which surrounded Paris in the Middle Ages, and formed a great attraction to the French monarchs on account of the excellent hunting they provided. From the long avenue there are interesting views of Paris, with the Eiffel Tower conspicuous, and on fine sunny days it has the fantastic aspect of a city of palaces and temples. On emerging from the forest of very indifferent trees, the road crosses the Seine, and one turns to the right at once for Conflans-Ste. Honorine, where the ruins of its two castles, with an old tower conspicuous, look out over the soft green of the willows bordering the river. The late Gothic church, with a tower of the twelfth century, contains a picture attributed to Zurbaran, a Spanish artist of the seventeenth century who was Court painter to both Philip III. and Philip IV. The association of Conflans with St. Honorine has been mentioned in connection with Graville (Section I.). About eight kilometres north of Conflans the River Oise is crossed at PONTOISE, an historic town picturesquely situated on high ground above the river.
