Geography comments: "Gala Abu Ahmed is a fortress ruin in lower Wadi Howar, northern Sudan. It is located c. 110 km west of the River Nile on the southern margin of the Libyan Desert".
"According to various radiocarbon dates on pottery, the site was occupied between about 1250 and 400 BC, or in cultural terms, in late New Kingdom/pre-Napatan to Napatan times".

Habitat comments: "The Gala Abu Ahmed fortress, with its impressive stone bastions and walls, encloses an area of 120 × 180 m and stands up to 4 m high. The fortress was built on a sandstone outcrop on the lower terrace of the southern edge of a channel-like wadi, just east of the conjunction of two channels. The general layout of the fort and its massive construction suggest that it was a defensive fortification. The position of the fortress near the mouth of the wadi indicates that it served as a fortified caravan station, protecting and controlling important trade routes".
"Excavations in the south-eastern part of the interior space revealed a three-room building with an almost square layout measuring c. 10 × 9 m. In the north-eastern corner of the fortress, a large, complex building with a series of rooms and courtyards was unearthed. To the north of this building, two rotundas proved to be large storage facilities, most likely used as granaries. A concentration of different types of objects was found to the east, including Greek pottery, arrowheads, pieces of faience, and sandstone figurines. A fireplace was found along the walls of the fortress, along with a large stone circle in the northwest corner, c. 20 m in diameter".

Sampling comments: "Major excavations of the site were conducted between 2008 and 2012. After the layout of an excavation trench, usually subdivided into 2 x 2 or 5 x 5 m squares, the windblown sand and rubble were first removed from each square as no in situ structures were preserved in this layer. The structures exposed below were then further investigated by smaller sondages set up at crucial points. Excavated sediments were systematically dry-sieved using a mesh size of 3 mm".
