Blida (Arabic: ?) is a city in Algeria. It is the capital of Blida Province, and it is located about 45 km south-west of Algiers, the national capital. The name Blida, i.e. bulaydah, diminutive of the Arabic word belda, city.
Blida lies surrounded with orchards and gardens, 190 metres (620 ft) above the sea, at the base of the Tell Atlas, on the southern edge of the fertile Mitidja Plain, and the right bank of the Oued el kebir outflow from the Chiffa gorge. The abundant water of this stream provides power for large corn mills and several factories, and also supplies the town, with its numerous fountains and irrigated gardens. Blida is surrounded by a wall of considerable extent, pierced by six gates, and is further defended by Port Mimieh, crowning a steep hill on the left bank of the river.
The nearby Chiffa gorge is a habitat of the endangered Barbary Macaque, Macaca sylvanus; this habitat is one of only a few relict locations where populations of this primate are found.
The present town, French in character, has well-built modern streets with many arcades, and numbers among its buildings several mosques and churches, extensive barracks and a large military hospital. The principal square, the place dArmes, is surrounded by arcaded houses and shaded by trees. The center of a fertile district, and a post on one of the main routes in the country, Blida has a flourishing trade, chiefly in oranges and flour. The orange groves contain over 50,000 trees, and in April the air for miles round is laden with the scent of the orange blossoms. In the public gardens is a group of magnificent olive trees. The products of the neighboring cork trees and cedar groves are a source of revenue to the town. Sidi-Ahmed El-Kebir, Blida’s founder, is buried in Sidi El-Kebir (an area named after him). He founded Blida in the 16th century.
The city occupies the site of a military station in the time of the Romans, but the present town appears to date from the 16th century, in which it was founded, according to Baedeker, by Moors. A mosque was built by order of Khair-ed-din Barbarossa, and under the Turks the town was of some importance. In 1825 it was nearly destroyed by an earthquake, but was speedily re-erected on a site about a mile distant from the ruins. It was intricately rebuilt of interconnecting alleyways and streets, and was made accessible through the existing six major gates. The gates were as follows:Bab Er-Rahba
Today those gates no longer exist, but their names are still in use by people in Blida as reference points to locate streets, places, schools and businesses.
In 1867, another earthquake damaged Blida.
For a long time Blida Province has been home to a cluster of Berber-speaking towns including Djebailia, Beni Salah and Beni Misrah. Their Amazigh dialect is related to the Tamazight of the Atlas mountains. Blida is particularly close to the Kabyle varieties spoken east of Algiers Province and has traditionally been seen as an intermediate between Kabyle and the Chenoua language native to the northeastern part of the country.
