Then came another tower and lastly La Porte Bernier or Bannier, at the north west angle of the ramparts.
On this side the walls had been constructed in the days of the cross-bow, which shot a greater distance than the bow.

The towers here, therefore, were farther apart at the distance of a cross-bow shot one from the other, and the walls were lower than elsewhere.

On the northern side, looking towards the forest, were ten towers at a bow-shot's interval.

The second, that of Saint-Samson, was used as an arsenal.

The sixth and seventh flanked the Paris Gate.
On the eastern side were likewise ten towers at the same distance one from the other as those on the north.
