Abstract


Valencian old town –locally called Ciutat Vella- suffered a huge transformation along 20th century. In was almost the whole city in 1900, and became less than 5% of the urban area in 2000. There was not only a process of architectural replacement, but a complete series of plans trying to update the historic spaces. There were three specific stages for those town planning proposals, made by public administrations but not always as public execution. The first group was developed at the beginning of the century following hygienic principles, with public both planning and execution. A second group, in the middle of that time, collected a series of punctual urban corrections and a huge new urban axis -Avenida del Oeste-; all these specially built by private investors. The third, final group of interventions occurred after Bologna protections principles, and the specific treatment of degraded areas into city centre. In this last, the most recent interventions can be studied the hard influence of previous urban fabric in the process of creating new urban spaces. Both historic slots’ and blocks’ geometry provide the definition for further street sections; but, in the other hand, those new street edges must be geometrically balanced with the possibility of construction of the new buildings behind them: structural geometries and functional measures must be attended. So, in this paper a series of clarifying samples are shown about the processes of public urban renewal implementation built in Valencia along the last third of 20th century.
