Castle of Lamego

Castle of Lamego (Castelo de Lamego) is a medieval fortress in the town of Lamego, in northern Portugal's Viseu district. Three parts of the original stronghold survive today: a 12th-century keep, a stretch of the old wall, and a 13th-century cistern. Together they offer a clear window into the origins of the town.

What is the history of the Castle of Lamego?

The castle predates the Portuguese nation itself. Tradition credits it to the Moors, but the hilltop was fortified even earlier: an ancient Lusitanian fort stood here first, and the Romans later strengthened it. Several eras therefore layered onto one site, although the surviving remains date from the medieval Christian kingdom.

What can you see at the castle?

The keep (Torre de Menagem)

The main feature is the 12th-century keep. It stands about 20 metres tall and has a square plan. Narrow slits on its faces originally lit the interior. In the 16th century some were turned into windows on the orders of the last Count of Marialva, D. Francisco Coutinho, possibly to give the tower a residential function. One building thus shows two eras: defensive and Renaissance.

The cistern

The highlight is the 13th-century cistern, the largest yet discovered in Portugal. A powerful vault resting on thick pillars covers it, and the effect is of a huge underground cathedral. Master masons carved their monograms into the walls. The cistern gave the garrison a water supply, which mattered greatly during a siege.

A section of wall

A portion of the old defensive wall also survives. It helps you picture how the castle enclosed and protected the oldest part of town.
