The building of Janáček Theatre, the youngest of the buildings of National Theatre in Brno, was planned from the early 20th century. From 1910 to 1957, seven architectural competitions were held to find the best design and project of the building. Around 150 architects participated in the competitions, among them several notable exponents of Czech arts and architecture: Bohuslav Fuchs, Josef Gočár, Vlastislav Hofman, Josef Chochol, Pavel Janák, Jan Kotěra and others. The proposed designs span a wide range of architectural styles documenting the history and development of the Czech architecture in the first half of the 20th century. The styles include historicism, Art Nouveau, Cubism, modernism, Functionalism, Socialist realism and classicising Neofunctionalism.
