The Dicoter Plans Archive arises from the reorganization of a significant part of the deposits relating to town planning documents kept at the Ministry of Public Works. It is the result of an assignment entrusted by the General Direction of Territorial Coordination to the Milan Triennale as part of the RAPu - Network Archives of Urban Plans project. In fact, since 1994 RAPu has developed an original methodology for the cataloging of town planning documents, aimed at establishing a virtual archive of planning tools produced in Italy by the national unit to date. The creation of the Dicoter Plans Archive and the computerization of its resources represent a significant progress in the enhancement of documentary heritages of great socio-cultural importance and an important contribution to historical research, to critical reflection on urban planning techniques and tools, to a greater awareness in contemporary planning practices. The archive collects documentation relating to: 1. municipal plans prior to the urban planning law 1150/1942 and other works of public utility; 2. reconstruction plans; 3. general regulatory plans and manufacturing programs pursuant to Law 1150/1942; 4. territorial plans; 5. zone plans; 6. subdivisions; 7. detailed plans; 8. industrial areas; 9. public works (railways, roads, airports, ports, post offices, aqueducts, other works); 10. miscellaneous (town planning legislation, studies, analyzes, clearance ...). The materials available on this site belong to the first three sections of the archive.
