Seokguram Grotto and Bulguksa Temple. The Buddhist complex was founded in the 8th century under the Silla kingdom. The Seokguram Grotto, an artificial grotto constructed of granite, is a masterpiece of East Asian Buddhist art and contains a large statue of Buddha. The Bulguksa Temple was completed in 774. It comprises several wooden buildings on stone terraces. Both the temple and the grotto have been renovated several times, in line with traditional techniques. In 1995, Seokguram was added to the UNESCO World Heritage List together with the Bulguksa Temple. It exemplifies some of the best Buddhist sculptures in the world.
