Der Städtebau nach seinen Künstlerischen Grundsätzen : ein Beitrag zur Lösung moderner Fragen der Architektur und monumentalen Plastik unter besonderer Beziehung auf Wien
Camillo Sitte's 1922 Viennese treatise on city planning, published in Vienna by K. Graeser, argues that urban squares and streets should be shaped by artistic principles rather than geometric regularity. The four plates are figure-ground plans of European towns, with black church footprints and hatched buildings set against open squares, which a designer can use to study how enclosure and irregular placement create civic space.
