Banwolseong 반월성 in Gyeoungju 경주, the 1000-year old capital of Shilla Kingdom, used to be a fortress and palace whose ruins can be visited. The name, Banwol-Seong comes from its outline which was shaped like a crescent moon. Banwol means half moon and Seong fortress.
A tower of stone blocks is located to the north of Banwolseong. Even if the purpose of the tower built in the 7th century still remains disputable, many historians agree that it was a kind of observatory. Cheomseongdae 첨성대 was built in the reign of Queen Seonduk 선덕. A rapeseed field is located between Banwolseong and the tower.
It was very cold last sunday. Cold wind blows across the rapeseed field. The vivid yellow of the rapeseed flowers could not be seen. The lush green leaves remind frequent visitors that the rapeseed flowers were in full bloom in the field last spring instead.
