Blida (Arabic: البليدة|translit=al-bulaydah) 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.[1] The name Blida, i.e. bulaydah, is a diminutive of the Arabic word belda, city.
Blida is known as the city of roses because of the large number of roses in its gardens.
Blida lies surrounded with orchards and gardens, 190m (620feet) 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. Within Blida is Chréa National Park, one of the largest national parks in the country and part of the Atlas Mountains. 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; the habitat is one of only a few locations where populations of the primate are found.[2]
In Blida, there is a Mediterranean climate. The Köppen-Geiger climate classification is Csa. The average annual temperature in Blida is 17.9°C. About 791mm of precipitation falls annually.
No ancient center preceded the city. It was identified with the town of Mitidja in the Middle Ages which was ruined during the Beni Ghania campaigns. The present town was founded by Moors in the 16th century.[3]
The town was rebuilt according to a grid plan following an earthquake in 1825 on a site about a mile distant from the ruins.[4] It numbers among its buildings several mosques and churches, extensive barracks and a large military hospital. The principal square, the place d'Armes, 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.
A mosque was built by order of Khair-ed-din Barbarossa, and under the Turks the town was of some importance. It was intricately rebuilt of interconnecting alleyways and streets, and was made accessible through the existing six major gates. The gates were as follows:
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.[3]
Blida Province is home to a number of Berber-speaking tribes &towns. The Berbers of Blida are known as Djebailia and have been in the plains of Blida/Matija for thousands of years according to historians such as Ibn khaldoun. The tribes are Beni Salah(Ith salah)Beni Misrah(Ith Misra), Ghalia and many more. They speak Taqbaylit the language of the Kabyle which is the Berber language of blida close to the Kabyle varieties spoken east of Algiers Province, It is 95% identical and has traditionally been seen as an intermediate between Kabyle and the Chenoua language native to the north-eastern part of the country.
