Bílá labuť (in English 'White Swan') is a department store on Na Poříčí Street in central Prague, Czech Republic. It is considered to be one of the finest examples of interwar avant-garde architecture. It is recognised by the Prague Municipality as an architecturally valuable building and is protected as a cultural real estate monument. At the time it was opened in 1939, it was the biggest and most modern department store in Central and Eastern Europe. It is currently undergoing an extensive renovation.
