Visionary architecture is the name given to architecture which exists only on paper or which has visionary qualities. Étienne-Louis Boullée, Claude Nicolas Ledoux and Jean-Jacques Lequeu are one of the earliest examples of the discipline. But the work of Giovanni Battista Piranesi, Antonio Sant'Elia and Buckminster Fuller is also included. In the latter half of the 20th century, there were architectural design movements such as Archigram, Archizoom and Superstudio.
The architectural paintings of Giorgio de Chirico also are sometimes included in this category.
