The top of the hill has an elevation of nearly five hundred feet, and exactly at this point is built the citadel; the whole town lying between it and the sea.  The houses of Algiers have no roofs, but are all terminated by terraces, which are constantly whitewashed; and as the exterior walls, the fort, the batteries and the walls are similarly beautified, the whole city, from a distance, looks not unlike a vast chalk quarry opened on the side of a hill.

The fortifications towards the sea are of amasing strength, and with the additions made since Lord Exmouth’s attack, may be considered as almost impregnable.  They occupy the entire of a small island, which lies a short distance in front of the city, to which it is connected at one end by a magnificent mole of solid masonry, while the other which commands the entrance of the port, is crowned with a battery, bristling with cannon of immense calibre, which would instantly sink any vessel which should now attempt to occupy the station taken by the Queen Charlotte on that memorable occasion.

On the land side, the defences are by no means of equal strength, as they were always considered rather as a shelter against an insurrectionary movement of the natives, than as intended to repulse the regular attacks of a disciplined army.  In fact defences on this side would be of little use as the city is completely commanded by different hills, particularly that on which the Emperor’s fort is built, and was obliged instantly to capitulate, as soon as this latter had fallen into the hands of the French, in 1830.

There are four gates; one opening on the mole, which is thence called the marine gate, one near the citadel, which is termed the new gate; and the other two, at the north and south sides of the city, with the principal street running between them.  All these gates are strongly fortified, and outside the three land gates run the remains of a ditch, which once surrounded the city, but is now filled up except at these points.  The streets of Algiers are all crooked, and all narrow.  The best are scarcely twelve feet in breadth, and even half of this is occupied by the projections of the shops, or the props placed to support the first stories of the houses, which are generally made to advance beyond the lower, insomuch that in many places a laden mule can scarcely pass.  Of public buildings, the most remarkable is the Cassaubah, or citadel, the situation of which we have already mentioned.  It is a huge, heavy looking brick building, of a square shape, surrounded by high and massive walls, and defended by fifty pieces of cannon, and some mortars, so placed as equally to awe the city and country.  The apartments set apart for the habitation of the Dey and the ladies of his harem, are described as extremely magnificent, and abundantly supplied with marble pillars, fountains, mirrors, carpets, ottomans, cushions, and other articles of oriental luxury; but there are others no less valuable
