A historic building having long age is vulnerable and easily damaged especially by seismic force. The restoration of the damaged building to the original one difficult. Hence, preparedness for the damage becomes crucial. This paper presents a study on the effect of earthquake on the main prang in Temple of Dawn using dynamic analysis option in finite element program. The structural model of the building was subjected to nine modified past earthquakes waves which were divided into three groups as (1) near-fault ground motions with forward directivity, (2) near-fault ground motions with fling and (3) farfault ground motions. The wave modification was performed based on the earthquake spectrum in the area. The results showed that the fundamental natural period was 1.208 s. Under earthquake excitations, the maximum compressive stress occurred at joint between Pa Thaksin ground and facade was 14.7 MPa and the maximum tensile stress occurred at Pa Thaksin ground was 4.13 MPa. They were respectively higher than 2.68 MPa and 0.27 MPa of the allowable values. Therefore, the strengthening of the main prang should be considered to prevent the damage of main prang under the forthcoming earthquake situation
