In the west, near the boundary with Portugal, there are different fortifications, due to the wars and fighting that took place throughout the history. Some of them played a very important role during the Napoleonic Wars.
They are medieval constructions reinforced in the 17th and 18th centuries following the bastion fortresses model. If we look at them from above, their star shape, with moats and ravelins really grab our attention.
The defensive buildings in Ciudad Rodrigo, San Felices de los Gallegos or La Conception Fortress are the most important ones. In our neighbor Portugal we can also find a perfect symmetry in the villa of Almeida.
