Gwangseong

Gwangseong (Zhenian: 광성), formally the City of Gwangseong (Zhenian: 광성시), is the provincial capital of Zhenia's Gyeongcheon Province. Situated on the southeastern coast of the Danguk Peninsula and directly facing the North Zhenia Sea to its east, it is the thirteenth largest city in the nation by population, being home to around 3.2 million residents. It comprises of 8 districts and two counties administered under the municipal government of Gwangseong, and is part of the Prefecture of Gwangseong, in which the city hosts the Prefectural Seat. Being home to the largest port in the Danguk Peninsula, it has become one of the largest economic centers of the eastern Danguk Peninsula as well as the North Zhenian Sea.

Starting as a naval outpost of the Zhen dynasty at the mouth of the Gwangdong River at around 398 BC, the city grew to prominence as a major port in the West Hanmaric trade network during the Eastern Zhen and Jin dynasties when Chang Munmu established the base of operations for his anti-piracy operations during the later days of the Eastern Zhen, being situated at the eastern node of the trading network that extended as west as Abayad. The city has been a major trading port and eventually the home port of the Zhenian Navy since the early modern ages, being the historic starting point of many Shindanese expeditions across the Hanmaric Ocean. It has also grown into a massive shipbuilding and steelworks hub since the 15th century AC, being a major core of Zhenia's industrial revolution at the time. Despite losing its position as Zhenia's primary core of heavy engineering amid Zhenia's economic resurgence after the Second Great War, the city remained prosperous amid increases in maritime trade and transport as well as the influx of the aerospace industry in the later half of the 16th century AC.

Today, Gwangseong is a major trading, transport and trading hub in the Zhenian east coast: the Port of Gwangseong is the second-largest port in the nation by cargo tonnage after the Port of Jinhae, while it is a major terminus point for many of the nation's key expressways and railroads. The Bank of Munmu, founded in 908 AC, is one of the oldest banks in the world still in operation and has played a prominent role in engineering the city's prosperity. The city is home to the base of operations of many leading Zhenian high-tech companies, including Rotunda, Munmu Arsenal, MC&T Engineering and the secondary headquarters of the Jinmu Group.
