_St. Pierre or St. Père-en-Vallée._ The abbey church of St. Père-en-Vallée, founded by Clovis, is a fine building dating from the twelfth to the fourteenth century. It was commenced in 1150, under the direction of the monk Hilduard, and almost entirely rebuilt in the thirteenth century. Of the earlier construction there remains the lower part of the choir, with its heavy pillars, the aisles which surround the choir, and the chapels. The great square tower has been placed as early as 940, but may have been built a century later. The stained glass belongs to the thirteenth, fourteenth, and fifteenth centuries, the earliest being in the choir excluding the apse. In the south aisle of the nave is the tombstone (1037) of Robert, Archbishop of Rouen, son of Richard I., Duke of Normandy. Unique enamels of the twelve Apostles can be seen in the apsidal chapel. _St. Aignan_ is mainly a Renaissance church, with the chief entrance built in the fourteenth century. The windows are the most interesting feature. _St. Martin-au-Val_ is the church of the ancient priory of the abbey of Marmontier, and to-day the chapel of the Hôpital St. Brice--a curious building of the twelfth century, incorporating some remains of a great basilica previous to the tenth century. The crypt contains some Roman capitals of marble, stone sarcophagi, and the tomb of a Bishop of Chartres. _St. André_, an interesting ruined collegiate church, now a shop, built, about 1108, over two square crypts belonging to Early Christian times. There is a beautiful Romanesque door. _St. Foi_ is chiefly a Flamboyant church. It was desecrated with great profanity in the Revolution, and remained secular until it was reconsecrated in 1862. _The Hôtel de Ville_ is a Renaissance building, formerly the Hôtel Montescot (1614). It contains the _Museum_ of pictures, objects of art, ancient armour and tapestry, and also the _Library_. _The Bishop’s Palace_ is a seventeenth-century building. _Maison de Loëns_, built over a thirteenth-century crypt. _Maison du Médecin_, at No 8, Rue du Grand Cerf, is a beautiful specimen of Renaissance, with an inscription above the door, showing that it was built by Claude Huvé, who was a doctor (1501-1559). _Maison du Saumon_, at No. 10, Place de la Poissonnerie, was built in the fifteenth century, and is the most curious construction of wood in Chartres. A big salmon is carved on one of its beams. _The House of the Old Consuls_, in the Rue des Écuyers, is interesting as the cradle of the city’s municipal power, and in possessing a most picturesque outside staircase turret (sixteenth century), now called the ‘Escalier de la Reine-Berthe.’ Many other houses belonging to the Middle Ages and Renaissance periods refresh the eye in walking through the streets of Chartres. _The Porte Guillaume_ is the only survivor of the seven gates that formerly existed. It is flanked by two cylindrical towers of the fourteenth century, with restored machicolated battlements.
