Soba is an archaeological site and former town in what is now central Sudan. Three kingdoms existed in medieval Nubia: Nobadia with the capital in Faras, Makuria with the capital in Dongola, and Alodia (Alwa) with the capital in Soba.[1] The latter used to be the capital of the medieval Nubian kingdom of Alodia from the sixth century until around 1500. E. A. Wallis Budge identified it with a group of ruins on the Blue Nile 19 kilometres (12 mi) from Khartoum, where there are remains of a Meroitic temple that had been converted into a Christian church.[2]
In the 10th century Ibn Selim el-Aswani described the city as large and wealthy, but he probably never visited it and modern archaeological investigations show it to have been a moderate centre. Built mainly of red brick, the abandoned city was plundered for building material when Khartoum was founded in 1821. Since the 1990s, development from the growth of suburbs in Greater Khartoum has continued to pose a threat to the ruins.
