Between 1279 and 1325, King D. Dinis ordered the construction of walls to surround the settlement of Bemposta, which included an area of 352 metres (1,155 ft) perimeter, using the same methods and strategies employed in Miranda, with two flanked gates and corbels.

[1] In 1399, King D. João I donated Bemposta and Penas Róias to Rui Gonçalves Alcoforado.

[1] The castle began to be part of the possessions of Vasco Pires de Sampaio, Master of Carrazeda and Master of Vila Flor, in favour of his son Fernão Vaz de Sampaio in the 15th century.

[1] On 6 March 1758, following the writings of Father José Camelo Borges, in the Memórias Paroquiais, the town had a small wall that was referred to as a castle, where some of the residences lived.

[1] The fortifications have an oval plan that sprawl over the topography and extend into the settlement, but only the southern remnants are perceptible.
