Jeongja-dong (정자동, 亭子洞) is a large residential neighborhood in Bundang, a district in the city of Seongnam. It is divided into the administrative dongs of Jeongja1-dong, Jeongja2-dong and Jeongja3-dong. It is connected to the Seoul Subway at Jeongja Station via the Bundang line.
The name Jeongja (정자, 亭子), or Pavillion, was coined during the Joseon Dynasty by the official Lee Kyung-in (이경인, 李敬仁: 1575-1642), a member of the Jeonju Lee Clan. This branch of the royal family had been erecting family graves in this area since the time of Lee Kyung-in’s great-grandfather Lee Bang Su (이방수, 李彭壽: 1490-1525), a son of King Seongjong, the ninth ruler of Joseon. An esteemed official, Lee Kyung-in held several senior bureaucratic posts around the kingdom and was honored for his role in suppressing the revolt lead by Lee Gwal (이괄, 李适: 1587-1624). However the disgrace and shame he felt after Manchu forces successfully subdued the peninsula in 1636 compelled him to resign from the government and retire to the banks of the Tancheon. It was there that he had a pavilion built and whiled away his remaining days in leisure. In honor of the "village of pavilions" he enjoyed so much the community came to be called Jeongja-ri (Pavillion Village). It was also sometimes called by his pen name Jeongchon (정촌, 亭村) which shares the same meaning.
Throughout the Joseon Dynasty current day Jeongja-dong was part of the township of Dolma in Gwangju County. This remained unchanged despite the administrative reorganization carried out by Japanese colonial authorities in 1914 that redrew so much else of Korea’s map, including the Bundang area. In 1973, when the community of Seongnam was incorporated into a municipality, Jeongja-ri became one of its dongs. With the establishment of Budang in 1991, authority over Jeongja-dong was transferred to the new district. In 1996, following the completion of Bundang’s construction, Jeongja-dong was subdivided into smaller units to meet the administrative needs of the growing community. The new dongs were called Singi-dong, Jeongja-dong and Buljeong-dong. However in 2001 they were renamed to Jeongja1-dong, Jeongja2-dong and Jeongja3-dong, respectively.
Jeongja-dong has thirteen schools:
