Abstract

Construction era of Pungnabtoseong earthen wall is one of the most popular controversial issues in Korean archaeological research. For the evaluation of construction era, OSL dating was carried out using seven pottery pieces collected in each construction stage. From TL/OSL characteristics, and the results of absolute zeroing test and recovery test, it was proved that the pottery samples were completely bleached. The reliable paleodose was evaluated by using the SAR method with preheat at 220 oC, and the pottery OSL age was determined from the ratio of paleodose to annual dose rate. Considering the resultant OSL ages, archaeological context and the related 14C ages, the first construction era was determined as 294±52 yrs AD (1σ SE). Also we found that the enlargement of construction stage III was 328±30 yrs AD (1σ SE) and final construction was finished within 400±76 yrs AD (1σ SE). Therefore, it is suggested that the construction of Pungnabtoseong earthen wall was firstly started in the late 3rd century AD and several enlargements and repairs had been carried out, before the transfer of the capital of Baekje dynasty to Woongjin (Gongju) at 475 AD.
