History of the Galician granite industry

From an industrial point of view it was in the 20th century that granite became one of the most dynamic, rising industries in Galicia. Until the 70s the business basically consisted of quarrying, but from then on processing began to gain in importance. Extraction operations (quarries) were joined by the first processing plants.

The first business associations were set up.
In the mid-80s the processing business was consolidated in O Porriño (Pontevedrea) and the 90s saw the development of most of the stone machinery industry.

The Granite Cluster is among the 10 Galician clusters that participate in the Atclusters Galicia project supported by IGAPE (Regional Development Agency of Galicia), which enjoy recognition of excellence at European level (European Secretariat for Cluster Analysis) or national (Program of Innovative Business Groups of Minetur).
