Marvão is a Portuguese village and is located in the heart of the Serra de São Mamede, high Alentejo, in the Portalegre district. It is about 843m high and was designated at the time as Herminius Minor, due to the Herminian hills (Serra da Estrela), where Lusitanian tribes lived.
At the top of the mountain, we can see a rocky ridge, where the walls and towers of the castle are integrated, making Marvão a homogeneous ensemble, between human work and its own topography.
Speaking a little of its history, since the Roman period, the Marvão cliffs have been as a refuge or as a strategic military point. During the Muslim era, with the partially populated Roman settlement, the Vizir of Coimbra conquered the Ibn Marwan region and rebuilt the fortifications of the mountain. Afonso Henriques took the Moorish fortress in 1166.
