Algiers (al′jērz; Fr., Alger), a city and seaport on the Mediterranean, capital of the French colony of Algeria, is situated on the west side of the Bay of Algiers, partly on the slope of a hill facing the sea. The old town, which is the higher, is oriental in appearance, with narrow, crooked streets, and houses that are strong, prison-like edifices. Its crowning point is the Kasbah, or ancient fortress of the Deys, about 500 feet above the sea, now serving as barracks. The modern French town, which occupies the lower slope and spreads along the shore, is handsomely built, with broad streets and elegant squares. It contains the Government buildings, the central military and civil establishments, the residence of the governor-general and the officials of the general and provincial Government, the superior courts of justice, the archbishop's palace and the cathedral, various other churches, including an English church and library, the great commercial establishments, &c. A fine boulevard built on a series of arches, and bordered on one side by handsome buildings, runs along the sea-front of the town overlooking the bay, harbour, and shipping. Forty feet below are the quay and railway-station, reached by inclined roads leading from the centre of the boulevard. The harbour is good and capacious, enclosed by piers or jetties, and otherwise improved at great expense, and it and the city are defended by a strong series of fortifications. Algiers is well provided with educational institutions, including high schools or colleges for law, medicine, literature, mathematics, and natural science; besides normal schools, an observatory, public library, &c. Algiers is in every way far the most important place in Algeria. There is a large shipping trade carried on, especially with Marseilles, Cette, and some of the Spanish ports. Trade routes from the interior and also railways centre in Algiers, and the exports include grain, wine, cattle, wool, ore, tobacco, fruit, olive-oil, &c. Algiers is now an important coaling station The city possesses widely-extended suburbs. The climate, though variable, makes it a very desirable winter residence for invalids and others from colder regions. Though warm, it is bracing. There is a considerable rainfall (average 29 inches), but the dry air and absorbent soil prevent it from being disagreeable. The winter months resemble a bright, sunny English autumn, while the heat of summer is not so intense as that of
Egypt. The sirocco or desert wind is troublesome, however, during summer, but in the winter it is merely a pleasant, warm, dry breeze. Hailstorms are not infrequent, but frost and snow in Algiers are so rare as to be almost unknown. Pop. 172,397.
