Location

The Keep stands imposingly in the heart of the Historic Centre of Alter do Chão, in the district of Portalegre. Its dominant position grants it a notable presence over the locality and the vast surrounding Alentejo landscape. Indeed, from this structure, the view extends over the rolling fields, dotted with holm oaks and cork oaks, characteristic elements of the cultural landscape of Alto Alentejo.

Integrated into the oldest urban fabric of the village, the tower constitutes an unmistakable landmark, easily identifiable among the surrounding buildings. Its presence is a silent testimony to the history that shaped this corner of Portugal.

Historical Background and Symbolism

This robust construction dates back to a period of affirmation and consolidation of Portuguese territory, bearing witness to the need for defense and surveillance. Erected as the strongest and safest point of a defensive system, the Keep served as a last refuge in case of attack, protecting the most valuable assets and offering shelter to the garrison.

Its construction, presumably dating from the 14th century and linked to periods of border intensification, underlines the strategic importance of Alter do Chão. Over the centuries, the tower witnessed crucial events and was a pillar of local security and identity, symbolizing power and resistance.

Architectural Features

The Keep of Alter do Chão is distinguished by its solidity and the purity of its forms. It has a quadrangular plan, a common characteristic of medieval defensive buildings, constructed mainly from stone masonry, which gives it a sober and harmonious tone with the environment. Its thick walls and reduced openings are a clear indication of its primary protective function.

Its constructive elements reflect the technical mastery of the time, aiming for durability and resistance. Although its appearance is austere, the monumentality of the structure commands respect and evokes its importance as a sentinel of the region, preserving the marks of time.
