The houses have kept their ancient aspect, and are curious for their wooden walls, sharply pointed gables, steep roofs with tiny dormer-windows, and daring corbellings overhanging the narrow streets and canals. The only means of access to the outside which some of them possess is a foot-bridge passing over the canal. _Turn to the right into the Rue St. Leu, passing in front of the_ =Hôtel Dieu=. Rebuilt in the 17th and 18th centuries, except the St. John ward, which was built at the beginning of the 16th century in the Gothic-Flamboyant style, it is a spacious hall with two large roofs, the gables of which face the street. The vaulting is of wood, the ends of the beams being carved. The whole is in very bad condition. _After crossing six successive lines of canals offering_ picturesque perspectives (_especially the_ Rue de Ville _and_ Rue des Coches), _the tourist arrives at the_ =Citadelle=. The Citadelle, built in the 16th century, has since been dismantled and now serves as a barracks. The =Porte Monte-Ecu= (historical monument), built in 1531 under François I., is within its walls. It was through this Gate that the Spaniards entered Amiens in 1597. _To get a view of it, turn to the right after the Pont de la Citadelle and take the first street on the left (see detailed plan)._ [Illustration: PONT DE LA DODANE. _On right of Canal_, RUE D'ENGOULVENT. _On the left_, RUE DES MAJOTS. _In the background_, ST. LEU CHURCH.] _Return by the same way to the Rue St. Leu. A little beyond the Church of St. Leu, take the Rue Fernel on the right, in which several_ 15th century wooden [Illustration: RUE D'ENGOULVENT (ABOUT 1820). (_drawing by the Brothers Duthoit_).] houses are still to be seen. No. 33, known as the "Ramoneurs," is especially worthy of note, though greatly deteriorated. _Follow the Rue Fernel to the Place Samarobrive, to the left of which take the Rue des Bouchers_ (_photo below_--picturesque old houses, especially No. 33). _At the end of this street, turn to the right into the Rue Haute-des-Tanneurs, which is continued on the other side of the Place Fauvel by the Rue Basse-des-Tanneurs._ At the end of the Rue Basse-des-Tanneurs, see the ancient dilapidated façade (1493) of the =Hotel Morgan de Belloy= (_B on detailed plan_), and the =Château d'Eau= (_A on detailed plan_), dating _from the 18th century_. A natural history museum has been installed on the first floor. _From the Hôtel Morgan there is a_ =fine view= _of the Cathedral and the lower town_ (_photo page 55_). _If the tourist has time he should cross the Somme by the Pont St. Michel, then follow the Boulevard du Jardin des Plantes to visit the_ =Jardin des Plantes=, _which is on the right of the Boulevard_. [Illustration: RUE DES BOUCHERS.] _Retracing his steps he should turn to the right after the Pont St. Michel, and follow the Port_
