Stained glass window, chapter house, Monastery of Batalha, Batalha, Portugal, 2009. The Dominican Batalha Monastery (Mosteiro de Santa Maria da Vitoria de Batalha) is a magnificent example of medieval Portuguese architecture. In 1385, King John I vowed that if his outnumbered army defeated the Castilians at the important Battle of Aljubarrota, he would build a magnificent monastery dedicated to the Virgin Mary. Construction of the monastery, which combines late Gothic and Manueline architectural styles, began in 1386 but was not completed until c1517. It is practically the only Portuguese building that still has original stained-glass windows. King Manuel I commissioned many stained glass windows for several churches in Portugal and the monastery was the Portuguese centre for stained glass making in the 15th-16th centuries. Batalha monastery was designated a World Heritage Site in 1983.
