The House of the Black Madonna is a cubist building designed by Josef Gočár. It is currently in use as the Czech Museum of Cubism and includes the Grand Café Orient restaurant on the first floor.
The House of the Black Mother, sometimes referred to as Black Mother of the Lord, was designed and built between 1911 and 1912 on the corner of Celetná Street and Ovocný trh. 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. After many years altered use in the interwar period and under communist rule, the house was closed in January 2002 and re-opened after extensive restoration in November 2003.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
