The new Communist Party House, designed by engineer and architect Francesco Tomassi with the collaboration of Roberto Mariani, has been built between 1964 and 1967. The site, located in the centre of Pisa, close to Guerrazzi square, was a residential area undergoing redevelopment. The essential nature of the building was intentionally designed in opposition to the surrounding eclectic residential buildings, in order to underline its function. Indeed, the concrete structure has been designed according to the space fruition: the main access is characterized by its welcoming appearance recalling the openness to debates, which is typical of the political ideology. The lack of decorative elements, while enhancing the building elegance, was interpreted as a coherent expression of the opposition between the Party and the reactionary forces. The versatility of modular panels of the façade reflected the conceptual change towards progress and modernity. Moreover the openings, terraces and volumes confer dynamism and a sculptural plasticity to the façade.

The innovative architectural language was appreciated by the public’s opinion: the rigorous functionalism, the rational approach and the sober nature of this work, were perfectly consistent with Modern architecture.
