The Party Founding Museum is a museum located in Pyongyang, North Korea. The building was constructed by the Japanese occupation government in 1923. It was used as the South P'yŏngan Provincial Products Exhibition. After his return to Korea after World War II, Kim Il-sung is alleged to have founded the Korean Worker's Party in this building on October 10, 1945, and here were held many of that group's first meetings. Thus, in 1970 it was turned into a museum dedicated to his exploits. Nearby, and also part of the museum, is the modest house he inhabited during his early days as president of North Korea.
