Jangan District, established on July 1, 1988, is the northern district of the city of Suwon in Gyeonggi Province, South Korea. It is approximately 15 km. from central Seoul.
Jangan District lies in the north of Suwon. It is bordered by Uiwang to the north-west, Yongin to the north and east, Yeongtong District to the south-east, Paldal District to the south and Gwonseon District to the south west.
Jangan District's northern border, with Yongin, is the mountain of Gwanggyosan. At 582 metres above sea level,[2] this is Suwon's highest point.
Most of the streams passing through Suwon originate in Jangan District, on Gwanggyosan or other nearby peaks. Since Suwon is bounded to the east by other hills, the streams, chiefly the Suwoncheon, flow southwards through the city, eventually emptying into the Yellow Sea at Asan Bay. The entirety of Suwon is drained in this manner.
The administrative "dong" (wards) of Jangan District are as follow. These differ substantially from the postal "dong".
There are 25 municipal and 19 private kindergartens, 20 municipal primary schools, 13 municipal middle schools, 9 municipal and 3 private high schools, 1 college, namely Dongnam Health College and one university, namely Sungkyunkwan University's natural science campus, in Jangan District.
Jangan District is home to Suwon Civil Stadium, a multi-purpose sports complex which hosted the handball events of the 1988 Summer Olympics, and which is now home to KT Wiz baseball team and Suwon FC football team.[3]
The area also contains Manseok Park, a recreational area surrounding a small reservoir.
