Valença (also known as Valença do Minho) is a historic fortified town in Northern Portugal, strategically located on the southern bank of the Minho River, which forms a natural border with Spain. The town is best known for its impressive star-shaped fortress (Fortaleza de Valença), an extensive military complex with a perimeter of 5 km of walls, bastions, and moats that dates primarily from the 17th and 18th centuries, although some parts are from the 13th century. The historic centre is entirely enclosed within these formidable walls, featuring narrow cobblestone streets, traditional granite architecture, and several churches, such as the Romanesque and Gothic-style Igreja de Santo Estêvão. Due to its location, Valença historically served as a crucial defensive position against Spanish invasions.
