The National Monument at Vítkov on top of Vítkov Hill in Prague's Žižkov district is one of the most important buildings related to the development of Czechoslovak/Czech statehood.
It includes the third-largest bronze rider statue in the world, of Jan Žižka, who defeated the Catholic forces led by King Sigismund in 1420 at the Battle of Vítkov Hill. The Monument also includes the Ceremonial Hall, an exhibition entitled Crossroads of Czech and Czechoslovak Statehood, the Tomb of the Unknown Soldier and other exhibition halls.
The Monument was built from 1928 to 1938 in honor of the World War I Czechoslovak legionaries. After 1948, it was used to promote the communist regime. Between 1954 and 1962, it housed the mausoleum of Klement Gottwald. In 2000, the monument was acquired by the National Museum, which conducted a major restoration work. After over two years of reconstruction, the Memorial was opened to the public on 29 October 2009.
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.
