National Taiwan University (NTU or ''Tai-Da'') was established in 1928 during the period of Japanese colonial rule. NTU has produced many political and social leaders in Taiwan. Both pan-blue and pan-green movements in Taiwan are rooted on the NTU campus. The university has six campuses in the greater Taipei region (including New Taipei) and two additional campuses in Nantou County. The university governs farms, forests, and hospitals for educational and research purposes. The main campus is in Taipei's Da-An district, where most department buildings and all the administrative buildings are located. The College of Law and the College of Medicine are located near the Presidential Office Building. The National Taiwan University Hospital is a leading international center of medical research.
