Gyeongju was the capital of the ancient kingdom of Silla, which ruled about two-thirds of the Korean Peninsula at its height between the 7th and 9th centuries, for close to one thousand years. Later Silla was a prosperous and wealthy country, and its metropolitan capital of Gyeongju was the fourth largest city in the world. A vast number of archaeological sites and cultural properties from this period remain in the city. Gyeongju is often referred to as "the museum without walls".
