South Pyongan Province is located in the western half of the Democratic People's Republic of Korea although it reaches far to the north-east, almost spanning the width of the peninsula. The province borders North Pyongan Province and Chagang Province to the north, South Hamgyong Province to the east, Kangwon Province to the south-east, Pyongyang and North Hwanghae Province to the south as well as sharing a river border with South Hwanghae Province over the estuary of the Taedong river. The province's western border sits on the coast of the West Sea (Yellow Sea).
The region is diverse geographically; much of the eastern part of the region is dominated by mountainous terrain. In the north-eastern parts of the province, the foothills of the Kaema Highlands make up the majority of the landscape. In the west, the flat plains which cover most of the country's south-west, cover the province between the city of Tokchon in the north and the port city of Nampo in the south-west.
One of the most significant natural aspects of the province is the Taedong river which flows from Changjin Lake (Chosin Reservoir) in South Hamgyong through the province, through the centre of Pyongyang and out into the West Sea at Nampo.
The economy of South Pyongan is varied due to the vast differences in the terrain. Mountains areas such as the city of Tokchon are limited in by the landscape and so are often centres for heavy or light industry; although, some foothill areas have a small agricultural industry focused primarily on livestock or dry-field farming which negates the need for irrigation.
Western South Pyongan is dominated by agriculture, with some exceptions. Nampo, officially not part of South Pyongan but administered separately since 2010, is one of the largest ports in the country and also encapsulates the heavy industry-focussed towns of 'Chollima' and 'Tae'an'.
Elsewhere, the city of Pyongsong, capital of South Pyongan, was built as a centre for the science and technology industry and is home to the Pyongsong Science University and the Pyongsong University Medicine.
The West Sea Barrage is located near Nampo at the mouth of the Taedong River. The dam was completed in 1986 with the aim of irrigating the surrounding land, thus improving its suitability for agriculture, and separating fresh water from saltwater to increase the national supply of fresh drinking water.
The city of Sunchon was the site of an aerial battle in 1951 between the Royal Australian Air Force and the Chinese Air Force resulting in a decisive victory for the communist forces, allowing the DPRK and China to continue their advance south to the 38th parallel.
The Kaechon Revolutionary Site is dedicated to the '250-mile journey for National Liberation' which was undertaken by the President Kim Il Sung in 1925 from his hometown in Mangyongdae, near Pyongyang, to Manchuria.
The revolutionary site 'Konji-ri' is the site of the President Kim Il SUng's military headquarters for a time during the Korean War. His office and living quarters have been preserved - visitors (domestic and foreign) can visit the site and see the office used by the President during the military campaign as well as bullet holes in the building from a US air force attack on the site.
