A statement of independence
Batalha Monastery is a celebration of the Portuguese victory over Castile in the so-called Battle of Aljubarrota held nearby on 14th August 1385. The recently acclaimed King João I made a vow to the Virgin Mary on the eve of this battle that he would order the building of a monastery in case Portugal came out victorious, thus remaining independent. This circumstance allowed for an unprecedented flourishing of architecture, sculpture and stained glass during the forthcoming 130 years when Batalha became a centre of international artistic convergence.
