Our central office is located in the Vallés Occidental, in the city of Terrassa, Barcelona province.

Terrassa has its origin in the old Roman village of Egara and is a town with hundreds of years of history behind and a great cultural interest. The municipality occupies 74.6 km2 and hosts a population of 200.000 inhabitants.

To talk about Terrassa these days, is to talk about deep changes on public affairs, culture, heritage recovery, conservation and improvement of the environment, etc.

Within this environment of renewal and social participation, Alternativa 3 NGO develops its work.
