Info. Nossa Senhora da Graça Fort near Elvas, Portugal
Standing on a hill in eastern Portugal, the Nossa Senhora da Graça Fort has been called a masterpiece of 18th-century military architecture. The thick wall that surrounds the fortress is shaped in a star pattern, with pentagonal bastions extending out from the curtain wall at the corners.
