Castle of Arnóia

Castle of Arnoia is a medieval fortress perched on a hill with a rectangular tower, watchtower, and defensive walls surrounding the structure. The site features a single entrance gate and was designed to control and protect the surrounding territory from this elevated position.

The fortress was first documented in 1064 and served as an important military stronghold during the medieval period of castle building across Europe. It played a key role in defending and controlling this region during the High Middle Ages.

The castle displays Romanesque architectural features typical of medieval Portugal in this region. Visitors can observe the stonework and fortification style that reflect the building traditions of that era.

The site is easily accessible and offers free entry to all visitors with no admission restrictions. An information centre at the location helps guests understand the history and layout of the fortress during their visit.

In the 18th century the fortress experienced decline after local authorities moved their operations away from the location. This led to the village being abandoned for an extended period before restoration efforts brought renewed attention to the site.
