Some of Gyeongju's most famous sites relate to the Silla government's patronage of Buddhism. The grotto of Seokguram and the temple of Bulguksa were the first Korean sites to be included on the UNESCO World Heritage List, in 1995. In addition, the ruins of the old Hwangnyongsa temple, said to have been Korean's largest, are preserved on the slopes of Toham Mountain. Various Silla-era stone carvings of Buddhas and bodhisattvas are found on mountainsides throughout the city, particularly on Namsan.
