Sun Yat Sen Memorial House (simplified Chinese: 澳门国父纪念馆; traditional Chinese: 澳門國父紀念館) or Memorial House of Dr. Sun Yat Sen is a museum located in São Lázaro, Macau, China where former family members and relatives of Sun Yat-sen, the 'Father of Modern China' used to live. The House bears witness to his short but significant stay in Macau in the early 20th century where Macau serve as the starting point for Dr. Sun's travels around the world; it also act as an important venue in which he conducted revolutionary activities and finally as the ideal place he chose to settle his family in later years.
Known formerly as "Mansion of Sun", the House was built in 1912 as residence for his first wife, Lu Muzhen. It is located within walking distance of Lou Lim Ieoc Garden where Dr. Sun once stay during his later visits to Macau in 1912. Designed in mock-moorish style, the House is a three-storey high building with ornate verandahs and spacious courtyards.
Lu Muzhen settled down in the House in 1913 with their two daughters, Sun Yan (孙延), Sun Wan (孙琬) and son Sun Ke at Dr. Sun's request. She lived in Macau for 40 years before passing away at the age of 85 on 7 September 1952. A son-in-law of hers and a granddaughter lived over a long period of time and died in Macau too. Another notable mention is Dr. Sun's elder brother Sun Mei (孙眉) and his wife moved to Macau in 1913 and settled in together with Lu Muzhen, where he conducted business and organised a fishermen's association in Macau. Sun Mei died in Macau at the age of 60 on 11 February 1915.
