Federální shromáždění, Museum in Vinohrady, Prague, Czech Republic.

The Nová budova Národního muzea, originally the Prague Stock Exchange, was built in 1936–1937 to a design by Jaroslav Rössler. In 1968–1973 Karel Prager, Jiří Kadeřábek and Jiří Albrecht added a suspended glass wall—then the largest in Czechoslovakia—and a Vierendeel truss above the older building. In front stands Vincenc Makovský's bronze sculpture New Age, made for Expo 58.

The original building was Jaroslav Rössler's Prague Stock Exchange, opened on 24 February 1938. After 1948 the National Assembly moved in from the Rudolfinum, and in 1965–1966 Karel Prager, Jiří Kadeřábek and Jiří Albrecht won the competition to extend it; the work ran from 1968 to 1973. From January 1969 the Federal Assembly met here until 1992, and from 1995 to 2009 Radio Free Europe/Radio Liberty occupied the building.

The building served as a center of political decision-making in Prague for decades and remains a symbol of the nation's journey through different systems. Visitors who pass by recognize its role as a landmark where the country's direction was shaped during crucial moments.

The location is easily accessible on foot and situated in a central neighborhood with good public transportation connections. Plan your visit with enough time to explore the architectural details from multiple angles and viewpoints.

The extension was built over the original 1936–1937 stock exchange by Jaroslav Rössler, which remained in place beneath Karel Prager's structure. In front stands Vincenc Makovský's bronze sculpture New Age, made for Expo 58 in Brussels and awarded the Grand Prix; a copy stands at the Brno exhibition grounds.
