Abstract:The Hall of Geology is one of the three landmark buildings built by the National Peking University in the 1930s, and it is also the only building that belongs to a single faculty (the Geological Department of Peking University). The completion of the Hall of Geology depended on three conditions: the first, in the early 1930s, the Peking University purchased Songgongfu(松公府) , a large area between the College of Science and the College of Arts at the Peking University, which provided the basis for the campus expansion; the second, The Cooperative Research Grant agreed upon by the Peking University and China Foundation for the Promotion of Education and Culture solved most of the construction funding problems; the third, research professors Ding Wenjiang and Li Siguang, who were jointly employed by the Peking University and China Foundation, became the direct promoters of the construction of the Hall of Geology. The Hall of Geology, designed by Liang Sicheng and Lin Huiyin, was completed in 1935 in a modern style with traditional Chinese characteristics, providing the Geological Department of Peking University with good teaching and scientific research facilities, which can be regarded as a symbol of the heyday of the development of the Geological Department of Peking University in the first half in the 20th century. After the outbreak of the War of Resistance Against Japanese Aggression, the Hall of Geology fell into the hands of the puppet government controlled by Japan, and was successively occupied by several institutions. When Peking University returned to Peking from Kunming in 1946, the Geological Department was moved back to the Hall of Geology, and books and instruments were added. In 1952, when the national university faculties were reorganized, the Hall of Geology was used by the newly formed Beijing Geological College, and the glory of the Geological Department of Peking University came to an end for the time being.
