The town of La Roche-Pont (at that time the abbey alone preserved the name of Saint-Julien, and the town had adopted that of the castle) had been deemed by Charles the Bold worthy of special attention. Recognising the advantageous site of the place and the importance of its strategic position, this prince had adapted the ancient defences to the new mode of attack. The old castle of La Roche-Pont, several times repaired, still showed some of its defences dating from the end of the twelfth century, the donjon being particularly well preserved; but the abbey and the entire plateau had been surrounded by a new wall by Philip, about 1380, and the town had been rebuilt within this enclosure, the right bank of the larger stream being completely abandoned. At the end of the fourteenth century there existed only a suburb on the slopes of the plateau along the left bank, and this suburb had no other defence than a wall of inconsiderable strength on the north. The great-grandson of Anseric, Sieur de la Roche-Pont, having died without male heirs, the fief of La Roche-Pont had reverted to the Duke Philip, who, as well as his successors, appointed the governors of the town and castle, henceforth a ducal domain. The enclosure of the town had been rebuilt in great part on the Roman foundations. It consisted of a substantial wall rising about twenty-four feet above the outside ground level, without machicoulis, strengthened with cylindrical towers thirty-six feet in height surrounded by machicoulis and covered with conical roofs. Machicoulis formed also the upper defence of the curtains and towers of the castle, whose plan had not been changed. This place had not suffered any attack since the date of these new works, and it was intact under Charles the Bold. During his struggle in the north with the people of Ghent and Hainault, and as a precaution against the intrigues of Louis XI., he had thought it needful to put the town of La Roche-Pont in a good state of defence. Now, limited though its efficiency was, the artillery of the king of France already played a sufficiently important part in sieges to render it necessary to provide against its effects. The duke therefore raised several boulevards to replace the walls and receive artillery. (Fig. 48.) [Illustration: FIG. 48.--THE TOWN OF LA ROCHE-PONT IS FORTIFIED BY CHARLES THE BOLD.]
