The high amount of interwar architecture in Hradec Králové gave rise to the city's nickname: Salon Republiky. It is a mixture of Cubism, Art Deco and the international style. In addition to Prague architects, local architects left their architectural marks in the city, which was extensively expanded after 1918 and the foundation of Czechoslovakia. The mayor František Ulrich was decisively involved in this project. The term Salon Republiky is intended to express, that since 1918 the urban plans and buildings were organised by Czech authorities, architects and urban planners and no longer by Austro-Hungarian institutions.
An architectural guide is available for Hradec Králové, called KAM, Královéhradecký architektonický manuál.
