Die Städte-bau nach seinen künstlerischen Grundsätzen : ein Beitrag zur Lösung modernster Fragen der Architektur und monumentalen Plastik unter besonderer Beziehung auf Wien
A German-language treatise on city planning by Camillo Sitte, published in Vienna in 1889 by Graeser, arguing that urban squares and streets should be shaped by artistic principles rather than geometric regularity. The four figures are schematic plan diagrams in which dark solid blocks mark monuments and buildings set among hatched street blocks and open plaza space, with letters labelling positions. A designer could take from them a clear figure-ground method for arranging a civic centre, showing how a single monument placed off-axis within irregular surrounding masses creates an enclosed open square.
