Ballon in the long list of peninsular strongholds. The hill forms a prominent feature in the surrounding landscape; and the view from the height itself, over the wooded plains and gentle hills of Maine, is wide indeed. He who held Ballon against the lord of Normandy, the new lord of Le Mans, might feel how isolated his hill-*fort stood in the midst of his enemies. To the south Le Mans is seen on its promontory; and, if the mighty pile of Saint Julian's had not yet reached its present height, yet the twin towers of Howel, the royal tower by their side, the abbey of Saint Vincent then rising above all, may well have caught the eye even more readily than it is caught by the somewhat shapeless mass of the cathedral church in its present state. To the north and north-west the eye stretches over lands which in any normal state of things would have been the lands of enemies, the lands of the houses of Montgomery and Bellême.

A second ditch surrounds the castle itself, and is carried
