After the annexation of ThessalyThessaly, a period follows in Greece during which pure town planning issues retreat to second place, in comparison with public works, infrastructures, and the production sector. Under a new modernizing political leadership, the country attempts to change its industrial profile, an effort which is violently interrupted by a major financial bankruptcy and a military defeat just before the end of the nineteenth century. All these developments are reviewed in this chapter. The disastrous bankruptcy, the imposition, once again, of foreign financial control, and the slow pace of industrialization prevent the country to modernize and to introduce town planning innovations, at a time of major changes in the discipline and practice of planning of western European countries. This is the reason why in this chapter the author refers to influential writers like Josef StübbenStübben and Camillo SitteSitte and to the dialogue that ensues in Europe. The “science” of town planning is consolidated, the planning profession grows and professional associations are being formed. In Greece, while AthensAthens and the cities of ThessalyThessaly are rapidly changing, planning is limited to endless town extensions and ad hoc amendments of existing layout plans.
