Unhyeongung, Royal palace in Jongno District, South Korea.

Unhyeongung is a palace complex with several traditional Korean buildings such as Norakdang, Noan-dang, and Irodang arranged around landscaped gardens and stone pathways. The compound preserves the architectural style and spatial layout typical of royal family residences during the Joseon period.

The palace was the residence of Heungseon Daewongun, father of Emperor Gojong, and became a center of power during the late Joseon period in the 19th century. Its importance grew as the Daewongun's family exercised increasing influence over imperial affairs.

The name Unhyeong comes from the hill called Unhyeon, where the Seoun-gwan, the royal astronomical observatory, stood. Norakdang, the largest hall, was where Gojong and Empress Myeongseong held their wedding on 21 March 1866; a reenactment is staged there each spring and autumn. Mannequins in the halls wear clothing of different social stations.

The complex is entered from the street on its west side, where an open dirt yard faces the road; the three halls stand in a row to the east, from south to north Noandang, Norakdang and Irodang, linked by covered corridors. The site is a museum open to the public free of charge. A small row of rooms called Sujiksa, to the right of the entrance, once housed servants and guards.

The name Unhyeongung comes from Unhyeon, the hill named for the Seoun-gwan, the royal astronomical observatory that stood in front of it. The compound once stretched as far as today's Duksung Women's University and Unhyeon Elementary School; the western half of the site is now an empty yard facing the road.
