Sun Yat Sen Nanyang Memorial Hall

Sun Yat Sen Nanyang Memorial Hall is one of the few surviving examples of villas that were once common sights in British Singapore. As its name clearly suggests, the building is strongly linked to the Chinese revolutionary Sun Yat Sen (孙中山). Moreover, it serves as a reminder of the contributions of Chinese pioneers and their historic connection to the 1911 Chinese Revolution (辛亥革命).
