Cooperation project between the National Heritage Institute and the DAI ROME: Jouggar project (Zaghouan governorate)

Project Coordinators: Hamden Ben Romdhane and Ralf BockMann

Laser scanner and photogrammetric survey

The INP (Institut National du Patrimoine) in Tunis and the DAI – Deutsches Archaologisches Institut (German Archaeological Institute) in Rome have been conducting a project to study the archaeological site of Jouggar, Tunisia, since 2018.

In 2019, an integrated laser scanner and photogrammetric survey was carried out in order to obtain three-dimensional ultra-high resolution artefacts.

The site consists of an external part, a Byzantine fortress and an underground part, a Roman nymphaeum.

The external part is acquired by laser scanner and photogrammetry both terrestrial and drone.

For the internal part, the laser survey is integrated with a very high resolution photogrammetric survey carried out downstream of the installation of a light lighting set.

The result is a highly detailed point cloud and an extremely resolute 3D model.

Historical information (R. Bockmann and H. Ben Romdhane)

Jougar is located on the slopes of a 370 m high mountain range, where the Ain Jougar spring originates. It is located 15 km south of Thuburbo Maius and 90 km from Carthage. According to current knowledge, the water from this spring was collected in the monumental Nymphaeum from the Severian period onwards and was fed into the aqueduct of Zaghouan, which supplied water to the ancient city of Carthage through a pipe with a total length of 128 km. During the Byzantine period, in the 6th century AD, the Nymphaeum was secured by a fortress, which was restored in the Middle Ages and the 19th century. This aqueduct continues to be functional to this day and is included with the entire Zaghouan-Carthage complex in the UNESCO World Heritage List.
