Silla (; Old Korean: 徐羅伐, Yale: Syerapel, RR: Seorabeol; IPA: ) was a Korean kingdom that existed between 57 BCE and 935 CE and was located on the southern and central parts of the Korean peninsula. Silla, along with Baekje and Goguryeo, formed the Three Kingdoms of Korea. Silla had the lowest population of the three, approximately 850,000 people (170,000 households), significantly smaller than those of Baekje (3,800,000 people) and Goguryeo (3,500,000 people).

Gyeongju (, ), historically known as Seorabeol (, ), is a coastal city in the far southeastern corner of North Gyeongsang Province, South Korea. It is the second largest city by area in the province after Andong, covering with a population of 264,091 people . Gyeongju is southeast of Seoul, and east of Daegu. The city borders Cheongdo and Yeongcheon to the west, Ulsan to the south and Pohang to the north, while to the east lies the coast of the Sea of Japan. Numerous low mountains—outliers of the Taebaek range—are scattered around the city.
