Ethiopia has many undiscovered archaeological sites. Possibly only ten percent of these have been excavated. All the time new discoveries are made. During a recent visit to Axum I learnt that these ruins are not part of the castle of Queen Makeda of Sheba. Ethiopian and German archaeologists expect that they were part of the castle of the 16th century AD King Khaleb. They hope to find those of the Queen of Sheba underneath these ruins.
