Yeonhui-dong, Seoul

Yeonhui-dong (Korean: 연희동) is a dong (neighbourhood) at the center of Seodaemun District, Seoul, South Korea. It is an area in Seoul near Yonsei university, and actually the name Yonsei comes from the combination of Yeonhui (the former Yonhee College) and Severance (the former Severance Union Medical College, Severance Hospital).

A strategic position during the Korean War (Hill 104), the area is bordered by Hongjecheon to the West (a stream overlooked by an important expressway), Ansan to the East (the mountain where Yonsei University is located), and Yeonnam-dong (Mapo District) to the South.

Seodaemun District office is situated at the top of this triangle, along with the Seodaemun Health Center (서대문 보건소) and the Seodaemun Youth Center (서대문청소년수련관), with its public swimming pool.
