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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
