Camillo Sitte (17 April 1843 – 16 November 1903) was an Austrian architect, painter and urban theorist whose work influenced urban planning and land use regulation. Today, Sitte is best remembered for his 1889 book, City Planning According to Artistic Principles, in which he examined and documented the traditional, incremental approach to urbanism in Europe, with a close focus on public spaces in Italy and the Germanic countries.
