For 1000 years, up until the 10th century, Gyeongju was the capital of the Silla Dynasty. Nearly 1000 years later, Gyeongju is an open-air museum. Those keen on Silla culture or archaeology will be in heaven viewing the remains of temples, tombs, shrines, palaces, gardens and castles. In the centre of town, Tumuli Park is a huge walled area with 20 royal tombs. A few hundred metres away, Cheomseongdae is one of the oldest observatories in Eastern Asia. The crowning glory of Silla temple architecture is Bulguksa, a magnificent temple built on a series of stone terraces about 16km (10mi) from the town. The eaves and internal painting of this gorgeous temple are one of the artistic highlights of Asia. High above the temple, a seated Buddha gazes over Gyeongju from Seokguram Grotto.
