The oldest of the three Bangkok campuses, Bangkok Noi Campus is located on 28 acres (12 hectares) and is home to the original medical school attached to Siriraj Hospital, founded by H.M. King Chulalongkorn of Thailand in 1890 which over time expanded into Mahidol University. The campus has retained its academic focus on medicine, revolving around the Siriraj Hospital complex.
