Cantacuzino Palace
Built in 1901-1903 for Gheorghe Grigore Cantacuzino, mayor of Bucharest and former prime-minister. After his death, the building was inherited by his son Mihail G. Cantacuzino, who died prematurely in 1929. Mihail's wife Maria remarried in December 1939 with music composer George Enescu. The building - known as Cantacuzino Palace at the time - hosted the Presidency of the Council of Ministers in the eve of World War II.
After the death of George Enescu in 1955, his wife stated in her will that the palace would host a museum dedicated to the artist. In 1956, 'The National Museum George Enescu' was established.
