The House of the Black Madonna is a cubist building in the "Old Town" area of Prague. It was designed by Josef Gočár. It is currently in use as the Czech Museum of Cubism.The House of the Black, sometimes referred to as Black Mother of the Lord, was designed and built between 1911 and 1912. Josef Gočár built the house as the first example of cubist architecture in Prague, and it remains probably the most celebrated. Even without historical details of the baroque building surrounding it, the House at the Black Madonna maintains the atmosphere of the neighborhood. The house was given its name by the stone sculpture that originally adorned one of the two Baroque buildings on the same lot.
