The castle was granted its first Foral (charter) by King Afonso Henriques in 1169.
Its construction was primarily aimed at controlling the border territory between the kingdoms of Portugal and Leon.
The village contains a pillory dating to the 16th century, located in the main square below the castle ruins.
Archaeological excavations at the site have revealed layers of occupation predating the medieval castle, including traces of Roman and Lusitanian presence.
The castle keep features a rare 'guelph' style crenellation pattern on its remaining parapets.
It is integrated into the 'Rede de Aldeias Históricas de Portugal' (Historical Villages of Portugal network).
Castelo de Linhares da Beira is a 12th-century military fortification located within the historic village of Linhares da Beira in the Serra da Estrela range. The castle occupies a strategic hilltop position at an altitude of approximately 800 meters, historically serving as a critical defensive point in the Beira region. It features a prominent square keep and sections of stone curtain walls that have undergone extensive conservation efforts. The fortress is categorized as a National Monument of Portugal. Its architecture reflects distinct Romanesque and Gothic influences typical of medieval Portuguese border defenses. Visitors can access the battlements to view the surrounding Mondego River valley and the interior mountain landscape. The structure is part of a larger historical village preservation project that maintains original stone houses and medieval street layouts.
