신라 was one of the Three Kingdoms of Korea, existing from 57 BC to 935 AD. It was located in the southeastern part of the Korean Peninsula and is known for its advanced culture, art, and architecture. The kingdom played a significant role in the unification of Korea and is famous for its Buddhist temples and the creation of the Hwarang, an elite warrior group. The capital of 신라 was Gyeongju, which is now a UNESCO World Heritage site. The kingdom is also recognized for its achievements in metallurgy, particularly the production of gold crowns and intricate jewelry. 신라's influence can still be seen in modern Korean culture and history.
