Fortress of Buhen, of the Middle Kingdom, reconstructed under the New Kingdom (about 1200 B.C.)
Buhen (Ancient Greek: ? Bohón) was an ancient Egyptian settlement situated on the West bank of the Nile below (to the North of) the Second Cataract in what is now Northern State, Sudan. It is now submerged in Lake Nubia, Sudan. On the East bank, across the river, there was another ancient settlement, where the town of Wadi Halfa now stands. The earliest mention of Buhen comes from stelae dating to the reign of Senusret I. Buhen is also the earliest known Egyptian settlement in the land of Nubia.
In the Old Kingdom (about 2686-2181 BCE), Buhen was the site of a small trading post in Nubia that was also used for copper working. The settlement may have been established during the reign of Sneferu (4th Dynasty). Nevertheless, there is evidence of still earlier, 2nd Dynasty, occupation at Buhen.
An archaeological investigation in 1962 revealed what was described as an ancient copper factory.
Buhen is known for its large fortress, probably constructed during the rule of Senusret III in around 1860 BCE (12th Dynasty). Senusret III conducted four campaigns into Kush and established a line of forts within signaling distance of one another; Buhen was the northernmost of these. The other forts along the banks were Mirgissa, Shalfak, Uronarti, Askut, Dabenarti, Semna, and Kumma. The Kushites captured Buhen during the 13th Dynasty, and held it until Ahmose I recaptured it at the beginning of the 18th Dynasty. It was stormed and recaptured by indigenous forces at the end of Egypt's 20th Dynasty.
The fortress itself extended more than 150 metres (490 ft) along the west bank of the Nile. It covered 13,000 square metres (140,000 sq ft), and had within its wall a small town laid out in a grid system. At its peak it probably had a population of around 3,500 people. The fortress also included the administration for the whole fortified region of the Second Cataract. Its fortifications included a moat three metres deep, drawbridges, bastions, buttresses, ramparts, battlements, loopholes, and a catapult. The outer wall included an area between the two walls pierced with a double row of arrow loops, allowing both standing and kneeling archers to fire at the same time. The walls of the fort were about 5 metres (16 ft) thick and 10 metres (33 ft) high. The walls of Buhen were crafted with rough stone. The walls of Buhen are unique as most Egyptian fortress walls were contructed with timber and mud-brick. The fortress at Buhen is now submerged under Lake Nasser as a result of the construction of the Aswan Dam in 1964. Before the site was covered with water, it was excavated by a team led by Walter Bryan Emery.

During 1962, an archaeological expedition of Buhen took place revealing a copper factory. During the excavation an unknown ore was found and analyzed further using modern techniques. The ore was originally made up of malachite however has become atacamite mixed with gold. With many factors going into a location being adequate for copper smelting, Buhen would have been an ideal location to produce small quantities of copper.
An Egyptian device called, "Fire Dogs," were used to generally prepare food. The exact usage of a fire dog is not known however, there is evidence that fire dogs involved fire and burning. A large number of fire dogs were found a Buhen, this discovery has been associated with the potential generation of copper by using fire dogs.
