Castle of Melgaço: a northern border sentinel in Portugal

The Castle of Melgaço (Castelo de Melgaço) stands in the parish of Vila, in the municipality of Melgaço, Viana do Castelo district, at the very north of Portugal. For centuries it guarded the crossing of the Minho river towards Galicia, and it is often described as the country's northernmost sentry post since the twelfth century.

Why was the castle built?

The fortress dates back to around 1170, when Afonso Henriques, the first King of Portugal, ordered its construction. At the same time he granted the settlement a foral, a royal charter that encouraged people to live and trade here. The young kingdom needed a strong point on its northern edge, and Melgaço was it. In 1212 the castle is recorded as having held back forces from the neighbouring Kingdom of León.

How did it change over time?

In the middle of the 13th century, after a period of civil conflict, Afonso III rebuilt the fortress. The result is the structure visitors see today: a Gothic reworking that kept the Romanesque layout of the inner courtyard, with the keep standing apart. Some accounts attribute parts of the work to the reign of Dinis (1279-1325). Around 1509 the defences were drawn in the Book of Fortresses by Duarte de Armas, under Manuel I, showing a village enclosure with three towers and two gates.

Melgaço also has a place in the story of the Sephardic Jews. In 1492, in the last years of John II, it was one of only five points on the Portuguese border through which Jews fleeing or expelled from Spain could enter the country. Later, during the War of Restoration that began in 1640, the castle was adapted to house artillery.

What can you see today?

Of the medieval castle, the main survivor is the square keep (Torre de Menagem), together with stretches of the old town walls. The keep is massive and has three floors in Gothic style, with narrow openings and a crown of battlements resting on elegant modillions, topped by a tiled roof.

Can you go inside?

Yes. The keep houses a small museum, the Núcleo Museológico da Torre de Menagem. Across its three floors it tells the history of the municipality from prehistory to the contemporary age. Climbing to the top rewards you with views of the surrounding mountains and of the historic centre of Melgaço, with its narrow streets and stone houses.
