With the Catalan industrial revolution, Terrassa became a major center of the textile sector in the late nineteenth and early twentieth centuries. Factories, warehouses, and residential buildings are concentrated in the city during the period of Modernism, with such remarkable examples as Masia Freixa and Casa Alegre de Sagrera.

For the citizens of Terrassa, the patrimonial elements become elements of identity. It is an active citizenry concerned with conserving and preserving these assets that are relics of the familiar past and translate into citizen pride. The link is based on associations of residents interested in heritage, which have the support and advice of entities such as the Heritage Board and the Center for Historical Studies of Terrassa. Terrassa City Council gives them a voice to express their opinions and assessments in expanding the inventory of Terrassa’s Cultural Heritage assets. In short, a review and group reflection to continue guarding the heritage with the best possible conditions in a correlative legacy from past to future.

The objectives from which the participatory process is set are:

• Facilitate the dissemination and understanding of the progress document of the MPOUM, and the background linked to the regulation of the Cultural Heritage of Terrassa.
• Achieve a higher quality plan/project: Collect different perspectives and proposals on the elements to be regulated and the criteria to be considered.
• Weave new relationships and improve governance with the affected agents of the territory, to facilitate their management and monitoring during the participatory process and the following stages of urban planning.
