The astounding number of Silla relics in Gyeongju is what makes this ancient city outstanding. Some of the sights are rather brief visits, such as the oldest Astronomy Tower in Asia and the largely re-constructed Anapji Pond. Yet the more time you spend in Gyeongju, you begin to recognize these incredibly diverse sites are all that remain of a powerful and advanced ancient civilization. If you have the great opportunity to visit Gyeongju make sure to visit the tombs and spend some time in and around Namsan mountain. Gyeongju being the ancient capital of Silla is a wonderful glimpse into a fascinating period of Korean history and is quite different from other regions of the country.
