Site C.01 on the citadel of Tungul (Old Dongola), the capital of Makuria was explored in 2007, 2008 and 2010 as part of the PCMA UW Dongola Project. A sequence of buildings was unearthed, dated to the Early Makurian (B.IX), Late Makurian (B.VI ) and Funj (houses) periods. The earliest structures represented later abandoned techniques of combining a core of sun-dried brick with fired bricks. In turn, the well preserved complex B.VI could be assigned to the 13th or early 14th century based on building materials, technique and pottery. The building was interpreted as a potential storehouse. A change of function occurred in the Funj period (17th century) with a series of domestic structures being built into the ruins. One of the finds was a 12-nummia coin of the Emperor Maurice, the sole such coin found south of the Third Nile Cataract.
