length of the loops was to enable bowmen to operate both while standing on the floor and on the seats, or even on temporary wooden platforms at different heights, and also to aim their arrows either high or low. The open staircases leading to the walls are carried up on the side next the town in the same way as those of Carcassonne.
In approaching the town from the north the Porte de Nimes ([Fig. 119]) is first seen in front, while a long vista of the northern wall with its towers stretches to the left, and the Tour de Constance terminates the view to the right. This gateway has as usual a large strengthening round tower on each side, containing guardrooms, &c., and is so arranged as to form an independent post.
Till the fourteenth century, gateways of this description were defended with folding gates, portcullis, machicolations (or apertures in the vault over the entrance passages), and with bretêches or hoardings projecting over the entrance, pierced with single, double, or even triple tiers of loopholes from which to attack the assailants. But there were as yet no drawbridges. At the Porte de Nimes evidences may be observed of a drawbridge, wrought with long balanced beams or levers passing through the wall, having been used; but it has evidently been introduced at a later time.
The walls of Aigues Mortes were entirely surrounded with a wet ditch (a few indications of which still remain), but it has for the most part been filled up and converted into a promenade. The ditch would be crossed with moveable wooden bridges which could be easily removed or destroyed.
A projecting stone balcony is corbelled out from one of the round towers of the Porte de Nimes. This was no doubt a station from which audience could be given to heralds or others wishing to communicate with the
