[1] This edict resulted in the settlement of the Military Order of São Bento in Avis, three years later, and the construction of a castle and fortified walls by Master-Prior D. Fernão Anes and Master D. Fernando Rodrigues Monteiro.

[1] By the middle of the year (10 July) D. Afonso II had granted the settlers of Avis a foral (royal charter) similar to that established for Évora, which was confirmed in August 1218 by the King.

[1] On 19 October 1654, friar Ambrósio Marques requested that the castle tower addorsed to the convent be demolished, since it threatened the destruction of the building: rubble had previously destroyed the chicken coop as it fell.

[1] By the end of the century, during the reign of King John IV, the towers in the northeast and southeast were demolished, and its materials used in the construction of two ravelins in the south and southwest.

[1] The Parochial Memories of 1758, signed by friar Gaspar Xavier Leitão, referred to a walled town, constituted by a regular square, and by the 17th century, two forts that protected the Èvora and the Santo António Gates.

António Pais da Silva Marques wrote to the DGEMN (8 November 1944), where he ridiculed the utopian ideal and pretension in reconstructing the primitive castle, since it would be necessary to demolition the entire settlement, including many of the addorsed houses.

On 20 January 1945, it was decided to survey the town and the walls, to analyze the possibility of demolishing some properties, but by 5 March 1947, the investigation had not been concluded nor were there any buildings designated for demolition.

Joana Procópio issued a request on 24 November 1953 for intervention by the DGEMN to restore the wall destroyed during a bad storm, since it put here residence in risk of destruction.

[1] A letter from João Lopes Cravitas dated 2 April 1965 solicited the authorization to consolidate the walls near many of the buildings in risk, a project that was budgeted for 500$000 escudos.

[1] This high place permitted observation across the vast landscape and visual communication with many of the local fortifications, including the castles of Alter do Chão and Pavia.
