[1] The Gasr Doga mausoleum is situated within the Tarhuna Gebel,[1][2] a fertile area characterized by its hilly terrain, located approximately 60 kilometers southwest of the ancient city of Leptis Magna.

During the construction of Gasr Doga, the nearby Gebel Tarhuna area was connected to Leptis through a road built under Aelius Lamia's proconsulate.

However, Gasr Doga's distinctive blend of styles and large scale reflect the burial practices of the Numidian culture, which borrowed from Hellenistic traditions.

[1] The podium's surface is covered with graffiti, ranging from contemporary Arabic inscriptions to older figurative drawings that depict hunting scenes.

Dating back to the fifth to twelfth centuries AD, these drawings reveal the artistic expression of the local Libyco-Berber culture, which is otherwise scarce in figurative representation.

In 1817, William H. Smyth documented his observations of the site, followed by Heinrich Barth's visit in 1849, Gerhard Rohlfs in 1887, Henry S. Cowper in 1897, and Federico Minutilli in 1912.

Further study seasons were conducted from 1999 to 2001 as part of research projects led by the Archaeological Mission of the Roma Tre University, under the direction of Prof. Luisa Musso.

A short flight of steps leads to a shaft, granting access to a series of corridors and vaulted chambers, which are identical in shape and size.

The column bases lack plinths, indicating an early date, and exhibit similarities with those from the Macellum at Leptis Magna, suggesting a comparable design.

The capitals feature a cylindrical kalathos adorned with acanthus leaves, displaying characteristics typical of early first-century Corinthian examples.

They are distinguished by their grey limestone material, with a pink patina, and feature a Neo-Punic inscription prominently displayed on a projecting band at the top.
