Gholaia (Bu Njem) |
||
|
There are many reasons to visit the ruins of ancient Gholaia or, as it is called today, Bu Njem (satellite). Admittedly, the remains don't look impressive when you approach them, but they belong to the most impressive monument of Libya: the Roman frontier zone, or limes. The emperor Septimius Severus (193-211) ordered the construction of a line of fortifications, which completely changed this part of Libya, the Tripolitania. |

Today, this is desert, but the area is not as arid as it seems. In fact, there is sufficient rainfall, but it is highly unpredictable and irregular. However, when the wadis have dams and dikes, the water can be regulated, and the area can be developed for agricultural purposes. This is what happened in the early third century. The first stage was to build forts like Gholaia. This map shows that it was a stereotypical castellum with barracks, a bathhouse, headquarters and a residence for the commander. | |
|
Other forts were at Ghadames and Gheriat al-Garbia. They were built by soldiers of the Third legion Augusta. This can be deduced from the towers near the main gate, which are not square, as is usual, but five-angled. This can only be found in settlements of the Third, which was based in Lambaesis in what is now Algeria. Gates like this can also be seen in Theveste. | |
|
The new forts controlled the main roads through the desert, and were situated near oases. On this photo of Gholaia's eastern gate, you can see the Bu Njem oasis in the background. It is about 100 km from the coast. By blocking access to the wells, the forts protected the country that was to be developed against large groups of nomads (e.g., the Garamantes). Against small bands, however, guarding the wells offered insufficient protection, so the farms that were to be built, had to have strong walls to keep invaders out for some time. Examples can be found at Gheriat esh-Shergia, Ghirza, and Qasr Banat. There were also watchtowers that signaled the arrival of intruders. The Limes Tripolitanus was a fine system, and many people settled in the Tripolitania as farmers, producing sufficient to make sure that towns like Sabratha, Oea (modern Tripoli), and Lepcis Magna prospered. Many settlers must have been veterans from the three forts. | |
|
Their culture, based on expert water management and vigilance, was to survive the Roman Empire. Of course, there were changes. In the late fifth, early sixth century, there were serious troubles, but the emperor Justinian reinforced the cities along the coast, built new towns (e.g., Theodorias) and the fortified farms were strengthened. An example is Suq al-Awty, which contains a small Byzantine church. | |
|
In the seventh century, the population converted to Islam and the Tripolitanian limes culture survived well into the eleventh century, when war between the Fatimid and Zirid dynasties resulted in invasions by the Banu Hillal nomads, who sacked countless settlements. Because many farms were abandoned, agricultural production fell, and the towns along the coast went into decline. | |
|
As a result, there were less people who could loot the abandoned forts and farms. (Oea is the exception.) The stones were never reused and were covered by desert sands. The settlements were forgotten until Italian archaeologists started to investigate them in the1920's and 30's. This is the main road of Gholaia, the cardo, which led from the main gate (background) to the headquarters. | |
|
This photo shows the remains of the headquarters, or Principia. Several columns surrounding the square court have been reerected by the French and Libyan archaeologists who studied the site in the 1970's. The quad may have been used as a market place, because no other site can been identified. There must have been a small prison too; its existence is implied in Ostracon #71. | |
|
The ostraca from Bu Njem are sherds on which reports and letters were written. Some of them were discovered in the room you can see in front. A little to the rear is the only scriptorium that has been identified in a Roman fort. Three examples of Bu Njem ostraca can be read here. | |
|
The Principia must have looked like this model from a limes settlement in a completely different part of the Roman empire, Waldgirmes in Germany. These buildings were the same all over the empire. Gholaia also had a square court surrounded by small rooms, a large transverse hall (basilica), and a shrine were the unit's standard was kept and venerated. | |
|
The remains of the basilica, seen from the place where most ostraca were found. The soldiers who served at Gholaia were recruited from all over Africa, like most legionaries of III Augusta. However, in 219, the emperor Heliogabalus disbanded the Third legion Gallica, and many soldiers of this unit were added to the African legion. This means that several soldiers in Gholaia were from Syria. | |
|
There is also evidence that soldiers from III Augusta were sent abroad. The Römisches-Germanisches Museum in Cologne shows a tombstone of a legionary from III Augusta, who must have visited Gholaia too. This room was the sacellum, the little shrine where the soldiers kept the standard of their unit. The unit's library must have been in one of the adjoining rooms. If the graffito shown below is reliable, the sacellum was pretty high. | |
