Samaniego’s houses are sheltered by the parish church, which was a fortress since its establishment in the 15th century. This church of the Assumption has a late Baroque façade and a Churrigueresque main altarpiece. The image of Nuestra Señora del Valle, patron saint of the village stands out.
Among its buildings are the Casa Palacio and the Casa de los Diezmos. At the village exit is the hermitage of the Virgen del Valle.
