There are several ancient stone masonry structures of great archeological significance in earthquake prone areas around the world. Kaʻba-ye Zartošt (Cube of Zoroaster) is a 14.2 m square in shape tower, which was built using white limestone blocks and dry joints. The tower dates back to the Achaemenid empire era and is located in the earthquake prone area of Pasargadae in Iran. Although, after approximately 2,500 years the tower is still standing, it is now in a severely deteriorated condition and may be vulnerable against future large in magnitude earthquakes. This paper aims to present the development of a three dimensional numerical model based on the discrete element method of analysis which was used to investigate the seismic behavior of the Cube of Zoroaster tower. To this end, the behavior of the tower to different ground shaking motions is discussed and the possible failure modes for each case are explored.
