Ancient ruins of Meroë, The Kingdom of Kush 
The Nubian city was the base of a flourishing kingdom whose wealth was due to a strong iron industry and international trade.  At the time, iron was one of the most important metals worldwide, and Meroitic metalworkers were among the best in the world. Meroë also exported textiles and jewelry. Their textiles were based on cotton, reaching its height of production around 400 BC. Nubia was also very rich in gold. It is possible that the Egyptian word for gold "nub" was the source of name of Nubia.
Meroë is on the east bank of the Nile about 6 km north-east of the Kabushiya station near Shendi, Sudan.
