The PREFECTURE consists of two contiguous buildings. One, modern, is fitted up as offices. The other, which is the Prefect's residence, was formerly the headquarters of the Intendant of Picardy. The latter building was erected in 1773-1774 from plans prepared by the Parisian architect _Montigny_. It was considerably damaged, both outside and inside, by bombardment (_photo opposite_). _Separated from the Museum by the Rue Puvis de Chavannes is the_ =City Library=. The LIBRARY is a modern building containing nearly 100,000 books and about 1,000 manuscripts, including several of great value. _(To visit apply to the curator)._ The colonnaded building in the rear was partly destroyed by bombardment. _On leaving the Rue de la République, take on the right the Rue Puvis de Chavannes (continued by the Rue des Louvets) as far as the Rue de Beauvais (photo below). Turn to the right. At the corner of the Rue de Beauvais and the Rue Frédéric-Petit is the_ =Lycée=. THE LYCÉE is located in the partly rebuilt structure which was formerly the _Abbey of St. John of the Order of Premonstrants_ (17th century); fine cloister. The façade of the modern portion, looking on the Rue Frédéric-Petit, was grazed by shell splinters. _Follow the Rue de Beauvais, continued by the Rue Alphonse Leuillier, as far as the_ HÔTEL DE VILLE (H _on detailed plan_); 18th century façade, finished in the 19th century. [Illustration: CORNER OF THE RUE DE BEAUVAIS AND RUE FRÉDÉRIC-PETIT NEAR THE LYCÉE] Bailliage and House of the White Gable _To the left of the Hôtel de Ville, take the Rue de la Malmaison, in which is situated the_ =Ancien Bailliage= (Old Bailiwick--_L on detailed plan)._ [Illustration: FAÇADE OF THE "BAILLIAGE." (_Bailiwick_)] To see it, the tourist should enter the courtyard of the City Fire Station, at the bottom of which, on the right, is a narrow passage leading to a tiny court, facing which is the curious façade of the house. Gothic-Flamboyant in style, it is richly decorated with Renaissance motifs (_photos_). A frieze of accolade-shaped arches with crockets runs along the building. Inside the arches, seven pure Renaissance medallions of men and women have been carved. Two small Renaissance angels dated 1541 appear below, between the two rectangular windows. On the left side of the building, a pretty dormer-window with triangular pediment breaks the monotony of the large slated roof, as is customary in civil Gothic architecture. Two Renaissance medallions of a man and a woman appear on the dormer-window. [Illustration: FAÇADE OF THE "BAILLIAGE."] Inside, interesting 16th century keel-arched timber work still exists in the audience chamber of the Bailiwick, the ceiling of which is hidden by a cloth. _Cross the Square behind the Hôtel de Ville. To the left of the Post-Office, take the Passage Gossart, at the end of which, under a vault, is the gate of a narrow alley leading to a small court._
