Party Foundation Museum, Political museum in Chung-guyok district, North Korea

The Party Founding Museum occupies a dark grey stone building on the south slope of Mt. Haebang in Pyongyang's Central District. The Japanese occupation government completed it on 30 November 1923 as the South Pyongan Province Merchandise Exhibition Hall, and its roof copies that of the Imperial Diet Building in Tokyo. Seven exhibition rooms on the first floor hold founding documents and artefacts; the second floor keeps Kim Il Sung's office, reception room and meeting room as they were.

The building was completed on 30 November 1923 under the Japanese occupation government and opened as the South Pyongan Province Merchandise Exhibition Hall, later serving as the Chojiya Department Store Pyongyang branch. After 1945 it housed the Central Organising Committee of the Communist Party of North Korea, where Kim Il Sung is said to have founded the Korean Workers' Party on 10 October 1945. Destroyed during the Korean War, it reopened as a museum in October 1970, and a monument to the party's founding was installed on 10 October 1975.

The building's name in Korean is Dang Changgŏn Sajŏkkwan, and its second floor keeps Kim Il Sung's office, reception room and meeting room as they were used. The first floor holds seven exhibition rooms of party-founding documents and relics. A house where Kim Il Sung lived in his early days on the peninsula stands on the grounds.

The museum stands on the south slope of Mt. Haebang in Pyongyang's Central District, and the grounds also hold the house where Kim Il Sung lived in his early days as president. The second floor keeps the office, reception room and meeting room he used, while the seven exhibition rooms are on the first floor. Foreign visitors normally reach the site through an authorised guide.

The building's roof is modelled on that of the Imperial Diet Building in Tokyo, a detail visitors often miss while looking at the dark grey stone facade. The museum also includes the modest house where Kim Il Sung lived in his early days as president, and a monument to the party's founding was installed on 10 October 1975.
