someone called this mosque a "roman"/"mamluk" building, i think it must be called a "romanesque"/"mamluk" building. roman style neans the period of architecture of roman empire and romanesque style was between 9. und 13. century. it's a medieval style. so you can find under the tag "roman" "roman" and "romanesque" buildings on various spaces. question: was the mosque at first a christian church, befor it becomes a mosque? the naves and the apsides remind me on romanesque basilicas in europe.
