The huge sacrifice that has been paid by Tigrayans is for the resurrection of Axum. As illustrated in the attached link it is recommended that the Tigray government builds, a new pan Africa City, which will be the best green city in Africa, around and close to Axum that will ultimately be the capital city of Axumite states. This city will be a metropolitan city in which all religions are tolerated and accommodated to freely practice their faith and build their own worship and prayer place. Therefore the Tigray Holocaust museum has to be built in Axum as a coroner stone for the new mega city to be built.
