UNESCO World Heritage Sites in Algeria

UNESCO's Description

In a mountainous site of extraordinary beauty, the ruins of the first capital of the Hammadid emirs, founded in 1007 and demolished in 1152, provide an authentic picture of a fortified Muslim city. The mosque, whose prayer room has 13 aisles with eight bays, is one of the largest in Algeria.

History

The fortress was built in 1007 by Hammad ibn Buluggin, the son of Buluggin ibn Ziri, and the founder of Algiers. The city became the capital of the Hammadid Berbers, and sustained a siege from the Zirid in 1017. In 1090, it was abandoned under the menace of the Banu Hilal, and was partly destroyed by the Almohads in 1152.

The Qalaa was described by Al-Bakri in the 11th century as a large and powerful military stronghold and a centre of commerce that attracted caravans from all over the Maghreb, Iraq, Syria, Egypt and the Hejaz. Ibn Khaldun also noted that the abundance of travellers was due to the wealth of resources offered to those interested in sciences, commerce and arts. The Qala attracted poets, sages and theologians.

UNESCO's Description

A traditional human habitat, created in the 10th century by the Ibadites around their five ksour (fortified cities), has been preserved intact in the M’Zab valley. Simple, functional and perfectly adapted to the environment, the architecture of M’Zab was designed for community living, while respecting the structure of the family. It is a source of inspiration for today’s urban planners.

History

The Mozabites ("Ath Mzab") are a branch of a large Berber tribe, the Iznaten, which lived in large areas of middle southern Algeria. Many Tifinagh letters and symbols are engraved around the Mzab Valley.

After the Muslim conquest of the Maghreb, the Mozabites became Muslims of the Mu'tazili school. The indigenous Christian population persisted until the 11th century. After the fall of the Rustamid state, the Rustamid royal family with some of their citizens chose the Mzab Valley as their refuge. However, the Rustamids were Ibadi and sent a preacher (Abu Bakr an-Nafusi) who successfully converted the indigenous Mozabites.

France conquered Algeria in 1830. The M'zab was annexed to France only in 1882 and reverted to Algerian indigenous rule in summer 1962 upon its national independence.

UNESCO's Description

Located in a strange lunar landscape of great geological interest, this site has one of the most important groupings of prehistoric cave art in the world. More than 15,000 drawings and engravings record the climatic changes, the animal migrations and the evolution of human life on the edge of the Sahara from 6000 BC to the first centuries of the present era. The geological formations are of outstanding scenic interest, with eroded sandstones forming ‘forests of rock’.

Geography

Tassili n'Ajjer is a plateau in south-eastern Algeria at the borders of Libya and Niger, covering an area of 72,000 km2. It ranges from 26°20′N 5°00′E east-south-east to 24°00′N 10°00′E. Its highest point is the Adrar Afao that peaks at 2,158 m (7,080 ft), located at 25°10′N 8°11′E. The nearest towns are Djanet on the southeastern edge and Illizi on the northern edge.

The plateau is of great geological and aesthetic interest. Its panorama of geological formations consisting of rock forests, composed of eroded sandstone, resembles a lunar landscape and hosts a range of rock art styles.

Geology

The range is composed largely of sandstone. The sandstone is stained by desert varnish, a thin outer layer of deposited metallic oxides that colour the rock formations variously from near-black to dull red. Erosion in the area has resulted in nearly 300 natural rock arches being formed in the south east, along with deep gorges and permanent water pools in the north.

The Tuareg Shield, an accumulation of terranes that formed during the Neoproterozoic era between 750 and 550 million years ago, encompassed the area of today's Ahaggar Mountains in Algeria, the Aïr Mountains in Niger, and the Adrar des Ifoghas in Mali. To the west lies the West African Craton, to the east the Saharan Metacraton.

UNESCO's Description

Timgad lies on the northern slopes of the Aurès mountains and was created ex nihilo as a military colony by the Emperor Trajan in AD 100. With its square enclosure and orthogonal design based on the cardo and decumanus , the two perpendicular routes running through the city, it is an excellent example of Roman town planning.

From the UNESCO World Heritage Centre (CC BY-SA IGO 3.0).

Geography

Located at the intersection of six roads, the city was walled but not fortified. Originally designed for a population of around 15,000, the city quickly outgrew its original plans and spilled beyond the orthogonal grid in a more loosely organized fashion.

At the time of its founding (c. 100 CE), the area surrounding the city was a fertile agricultural area, about 1,000 meters (1.0 km; 3,300 ft; 0.62 mi) above sea level. The original Roman grid plan is magnificently visible in the orthogonal design, highlighted by the decumanus maximus (east–west-oriented street) and the cardo (north–south-oriented street) lined by a partially restored Corinthian colonnade. The cardo does not proceed completely through the city but instead terminates in a forum at the intersection with the decumanus.

History

In the year 100 CE, the emperor Trajan founded the city as a Colonia. It was intended to serve primarily as a Roman bastion against the Berbers in the nearby Aures Mountains. It was originally populated largely by Roman veterans and colonists.

Despite its cultural and geographic distance from Rome, which most of its residents had never seen, Timgad invested heavily in Roman culture and identity.

Starting in the 3rd century, having enjoyed a peaceful existence over the decades from its founding, the city became a center of Christian activity, as well as a Donatist center in the 4th century.

At the end of the 4th century, during the Christian period, the diocese of Timgad enjoyed renown when Bishop Optat became the spokesman for the Donatist movement.

Visiting Timgad

Timgad is a town as well as the ruins of a Roman city in Northeast Algeria. The ruins are a UNESCO World Heritage Site. Timgad lies on the northern slopes of the Aurès mountains and was created as a military colony by the Emperor Trajan in 100 AD. It is an excellent example of the grid plan as used in Roman town planning.

UNESCO's Description

On the shores of the Mediterranean, Tipasa was an ancient Punic trading-post conquered by Rome and turned into a strategic base for the conquest of the kingdoms of Mauritania. It comprises a unique group of Phoenician, Roman, palaeochristian and Byzantine ruins alongside indigenous monuments such as the Kbor er Roumia, the great royal mausoleum of Mauretania.

Climate change

As a coastal heritage site, Tipasa is vulnerable to sea level rise. In 2022, the IPCC Sixth Assessment Report included it in the list of African cultural sites which would be threatened by flooding and coastal erosion by the end of the century.

History

Conquered by Ancient Rome, it was turned into a military colony by the emperor Claudius for the conquest of the kingdoms of Mauretania. Afterwards it became a municipium called Colonia Aelia Augusta Tipasensium.

The Roman city was built on three small hills which overlooked the sea, nearly 20 km. east from Caesarea (capital of Mauretania Caesariensis). Under Roman rule the city acquired greater commercial and military importance because of its harbour and its central position on the system of Roman coastal roads in North Africa. A wall of approximately 7,500 feet (2,300 metres) was built around the city for defense against nomadic tribes, and Roman public buildings and districts of houses were constructed within the enclosure.

UNESCO's Description

The Kasbah is a unique kind of medina, or Islamic city. It stands in one of the finest coastal sites on the Mediterranean, overlooking the islands where a Carthaginian trading-post was established in the 4th century BC. There are the remains of the citadel, old mosques and Ottoman-style palaces as well as the remains of a traditional urban structure associated with a deep-rooted sense of community.

Geography

The Casbah of Algiers takes its name from the citadel that overlooks it (designated in Arabic as القصبة, Al-Kasbah). Originally, the term "Casbah" referred to the highest point of the medina—the old city—of the Zirid era. Over time, it came to designate the entire medina, which was enclosed by the ramparts built during the Regency of Algiers in the 16th century.

The Casbah is located at the center of Algiers and forms its historic core. The city has historically occupied a strategic position, as its geographical location is central within Algeria and the Maghreb. Facing the Mediterranean Sea, it is built on terrain with a 118-meter elevation difference. At first glance, the Casbah appears as a cluster of houses built on a slope.

Climate change

Since the Casbah of Algiers is a coastal landmark, it is vulnerable to sea level rise. In 2022, the IPCC Sixth Assessment Report included it in the list of African cultural sites which would be threatened by flooding and coastal erosion by the end of the century, but only if climate change followed RCP 8.5, which is the scenario of high and continually increasing greenhouse gas emissions associated with a warming of over 4 °C., and is no longer considered very likely. The other, more plausible scenarios result in lower warming levels and consequently lower sea level rise: yet sea level rise would continue for about 10,000 years in all of them.

History

The Casbah of Algiers is an ancient medina with millennia-old origins, taking into account the site's Punic and Roman past. It is considered a cultural asset of global importance due to its ancient heritage and the history it embodies.

There are no traces of prehistoric settlement in the Casbah itself. However, given evidence of prehistoric habitation in the immediate surroundings (the Algiers Sahel), it is likely that such traces were simply obscured by the site's long-standing, dense, and continuous urbanization, and that it too was inhabited as early as the Neolithic period.

The exact date of the Phoenician establishment of ancient Algiers (Ikosim) remains uncertain, but it likely occurred after the late 6th century BCE.
