The existence of 400 churches has been recorded throughout the kingdom; most have yet to be located. Only seven have been identified so far, given the simple names of church "A", "B", "C", "E", the "Mound C" church in Soba, the church in Saqadi and the temple-church in Musawwarat as-Sufra. A hypothetical church was recently discovered in Abu Erteila in the western Butana. Churches "A"–"C" as well as the "Mound C" church were basilicas comparable to the largest Makurian churches. The Saqadi church was an insertion into a pre-existing structure. Church "E" and the church of Musawwarat es-Sufra were "normal" churches. Thus, the known Alodian houses of worship can be categorized into three classes.
