The Galician government put out to public tender the construction of this building. The winning project has been developed by RVR Architects, and the Park opened in 2011.
The Interpretation Centre is conceived as a long shape building, completely covered by granite slabs, naturally integrated in the landscape. The granite slabs produce lights and shadows over the façade that illuminates its different areas along the day. A large opening crosses the building from north to south, becoming a large outdoor reception area for visitors.
The ground floor of the building contains different public areas, such as the gift shop and cafeteria, reception area, and the spaces used for the permanent and temporary exhibitions. The upper floor contains the areas for the research and documentation of Galician rock art, and the day-to-day running of the Park.
