The Naturtejo Geopark of the Southern Meseta extends through the municipalities of Idanha-a-Nova, Castelo Branco, Nisa, Oleiros, Penamacor, Proença-a-Nova and Vila Velha de Ródão.

The vast geomorphological, geological, paleontological, and geomine heritage has elements of national and international relevance, such as Penha Garcia's fossil cannons, Penha Garcia and Monsanto's river cannons. In addition to the geosites, the Naturtejo Geopark has the International Tagus Natural Park and the Important Bird Areas (Penha Garcia), which testify to its ecological richness.

The ancient history of this region has endowed it with countless castles, churches and palaces, reaching a rare diversity in Portugal. The ruins of Civitas Egitania in Idanha-a-Velha, as well as the megalithic regions of Rosmaninhal, are poles of relevant archaeological interest.

Ancestral practices, living testimonies of the multiple singularities of Raian culture, have strong roots in the landscape. The status of "Most Portuguese Village of Portugal", given to Monsanto, and the Schist Villages, scattered throughout the Naturtejo Geopark, are symbols of this ethnographic wealth still very well preserved.
