The postern, H, was also the subject of lengthened consideration on both sides. This postern was necessary to secure the provisioning of the castle without encumbering the main entrance. Placed near the angle tower, U, which the enemy could not attack because of the steep escarpment of the plateau, the postern was well protected by that tower; moreover it was to be surmounted by a quadrangular work with double portcullis and double doors; lastly, a _braie_,[20] X, defended its approach. It was agreed, moreover, that the great central habitable part of the castle, erected on the remains of the square Roman towers, should be crenelated, and should command the curtain, and consequently the two entrances. Wells existed or were sunk at _p_.
Every part having been thus carefully determined, the works were vigorously prosecuted. The baron was always at hand, and persisted in seeing everything for himself. The north front of the bailey, and the chapel, E, were first begun. This exterior work did not greatly alter the appearance of things; but the donjon was next commenced. And when this tower, whose diameter was ninety feet, had reached an elevation of thirty, its aspect had become formidable. The townspeople viewed from a distance this huge mass rising on the point of the plateau, and began to wonder what their lord was intending to do with such an enormous tower. The abbot was somewhat disquieted; but he was so handsomely entertained at the castle that he gave no sign of dissatisfaction, especially as the great chapel of the bailey promised to be very beautiful.
Fortunately for Anseric, the Duke of Burgundy had at that time some rather important matters in hand--a misunderstanding with the King of France. Philip Augustus gave him considerable uneasiness, and at such a time he did not wish to alienate his nobility. More than two years thus passed without anything of serious consequence occurring to the lord of the castle. By that time the building was very nearly finished. We give a bird's-eye view of it (Fig. 37), taken from the north-east angle.

Nothing was talked of throughout the province but the beauty and strength of the new castle of Roche-Pont, and there were men of family in the neighbourhood, envious of the wealth and connections of Anseric, who did their best to represent him to the duke as an ambitious person, impatient of the feudal ties which bound him to his suzerain. It was even insinuated that the Sieur de la Roche-Pont, on the strength of his descent, aimed at nothing less than supplanting the duke; and that he had already begun to intrigue for that object with the king of France and with Pierre de Courtenai, who had married Agnes, sister of the last Count of Nevers and aunt of Eleanor; that his tenants were crushed under the burden of forced labours; and that the duke ought not to allow one of his vassals to oppress the poor people thus, in order to erect a castle surpassed in strength by none in Burgundy.
