These changes were decided with the help of professors Onat and Arda. The adviser was Prof. Dr. Paul Bonatz. The design included a great block over the colonnade of the mausoleum structure.
Upon the recommendation of Bonatz, this was removed completely, and a spiral-shaped, beamed ceiling for the mausoleum was agreed upon.
In the original plan, the walkway of the lions that is used today was to lead up to the mausoleum but this was changed. And, upon the jury’s advice, the idea of buildng a wall around the area was dropped.

BUILDING THE MAUSOLEUM OF ATATÜRK
Construction started on the fifth anniversary of the death of Atatürk on 10 November 1944. Great importance was placed upon the materials to be used, and the best quality materials were assembled from across the country. Stone and marble were brought from Haymana, Çankiri, Pinarbasi, Afyon, Çanakkale, Adana and Hatay. Stone of a pale yellow color that hardens with time were preferred. The 671,000 square metre area housed many sections.
