In one of the most beautiful places in Portugal: Monsaraz, an old knight's castle.
It is built of slate stone, on the crest of a hill. The castle offers a view of Spain and the flat, wide valley between the plateaus on both sides of the national border. This runs through the middle of the Barragem do Alqueva reservoir, in the lower Alentejo. | Portugal
A charm… But I am not exempt to express an opinion. :-D
