Macau Government House (Chinese: 竹仔室總督官邸; Portuguese: Palacete de Santa Sancha) or Santa Sancha is a building in São Lourenço, Macau, China. It is the state guest house of the Chief Executive of Macau. It is one of a few historic properties preserving Portuguese influence in Macau. Like many historic buildings it is clad in a pink like colour.
Prior to December 1999, the home was the official residence of the Governor of Macau since 1937. Its first resident during Portuguese rule was Artur Tamagnini de Sousa Barbosa.
Built in 1846 as a private home by Macanese architect Thomaz de Aquino, it was acquired by the Macau Government in 1926 and finally became the official residence replacing the Macau Government Headquarters, which then served as the Governor's office until 1999. Government House is now a state guest house. The building is an example of Pombaline style popular in Macau and Portugal in the 18th and 19th Century.
The home is built on a plateau (and foothills of Barra Hill) overlooking Sai Van Lake and bounded by private homes on several roads (Estrada de Santa Sancha, Estrada da Penha, Calcada da Praia and Avenida da Republica).
