IT appears that, from the position of the town of La Rochelle, it was not difficult for the vessels of an enemy to reach its walls, and even to penetrate its harbour; the latter was formed outside the town, and the access to it was by numerous gates. The entrance, nevertheless, was defended by two towers, which still exist, if not in all their original strength, yet exhibiting an aspect of defiance, and recalling recollections of times long past, such as few towns in France can now do. These towers, which stand, like Sir Bevis and Sir Ascapart, bold and menacing, and forbidding the entrance to any but a friend, are called La Tour de la Chaine and La Tour de St. Nicolas. The first is a rugged, round tower of great height and bulk, apparently of Roman construction; it was formerly called La Petite Tour de la Chaine, because it assisted its opposite sister, La Grosse Tour, to sustain the enormous chain which still, on occasion, closes the mouth of the harbour. The latter is now called St. Nicolas, and presents a most extraordinary and _old world_ appearance: higher than the first, its form is so irregular, that it would be difficult to decide what shape it could be called: round on one side, square on another, with little round, square, and octagon turrets rising out of it, the whole mass has the strangest effect imaginable. Within it is just as mysterious, having chambers built up and down, and communicating with each other in the most unexpected manner, so that the whole interior is a perfect labyrinth of galleries, cells, hiding-places, and rooms on different stages. This is just the sort of tower which seemed fitted for that inscrutable tyrant, Louis XI.; who wrote upon one of the windows, with a diamond, these words: "_O la grande Folie_!" alluding, it was believed, to what he considered his weakness, in having abandoned Guienne to his brother.
